[0045] Figure 1 This is a basic flowchart illustrating an intelligent tuning method for an LC filter according to an embodiment of the present invention. Detailed Implementation

[0046] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0047] Reference Figure 1 As an embodiment of the present invention, an intelligent tuning method for an LC filter is provided, comprising the following steps:

[0048] Step S1: Based on the meta-learning framework, sample historical LC filter debugging task data from the multi-task distribution, learn the distribution characteristics of parameters through a pre-trained machine learning model, and generate an initialization parameter set suitable for LC filter debugging tasks;

[0049] Step S2: Encode the inductance, capacitance, and quality factor of the LC filter into quantum states to construct a quantum particle swarm optimization and tuning model;

[0050] Step S3: Combining the concept of psychological field and knowledge distillation technique, the high-dimensional parameter space is mapped to the low-dimensional latent space to construct a parameter change trajectory database. The parameter change trajectory database is then used to perform time series modeling on the database to predict the optimal initial guess.

[0051] The meta-learning framework adopts a two-layer optimization structure. The outer layer optimization updates the initial parameter distribution through gradient descent, while the inner layer optimization simulates the gradient update process, including minimizing the cutoff frequency error and total harmonic distortion index of the current task, and outputting an initial parameter distribution that adapts to the condition of few samples.

[0052] With a small amount of sample data, meta-learning can quickly learn the tuning rules of LC filters, avoiding long trial and error from scratch and reducing the time and complexity of manual tuning.

[0053] The construction of a quantum particle swarm optimization and debugging model includes:

[0054] A quantum particle swarm optimization tuning model is used to describe the relationship between the performance of LC filters and tuning parameters.

[0055] Generating quantum states based on the initial parameter distribution includes: mapping the inductance value, capacitance value, and quality factor to the amplitude and phase of the quantum bit, respectively. The inductance value adopts a normalized logarithmic encoding form, the capacitance value adopts a piecewise linear encoding, and the quality factor is compressed to the [0,1] interval through the Sigmoid function.

[0056] The mathematical expression for quantum state encoding of inductance, capacitance, and quality factor is:

[0057] ;

[0058] in, Represents a superposition state of quantum states. The qubit amplitude corresponds to the inductance value, representing the relative contribution of the inductance to the quantum state. The qubit amplitude corresponds to the capacitance value, representing the relative contribution of capacitance to the quantum state. The amplitude of the qubit corresponding to the quality factor represents the relative contribution of the quality factor to the quantum state. The quantum state of inductance value, The quantum state of capacitance. The quantum state representing the quality factor;

[0059] The quantized parameter space is obtained, and the particle positions in the quantized parameter space are initialized by the particle swarm optimization algorithm. The initialization includes: adjusting the search direction of the particle positions through the quantum rotation gate based on the preset number of iterations and fitness change rate, and dynamically adjusting the inertia weight of the particle swarm. The inertia weight is used to control the speed and direction of the particle search.

[0060] The quantum rotation angle of the quantum rotating gate is dynamically calculated based on the gradient difference between the current parameters and the global optimal parameters, ensuring that the search direction adjusts as the optimal solution changes. The mathematical expression for the rotation angle is:

[0062] in, For rotation angle, Let be a function that maps the two input gradients to rotation angles. The gradient of the current parameters. The gradient of the global parameters.

[0063] The gradient difference reflects the gap between the current parameters and the global optimum, while the change in the rotation angle helps the particle to perform a more accurate search in the neighborhood of the optimum.

[0064] Breaking local optima using chaotic perturbation strategies includes:

[0065] During the convergence stagnation phase of the particle swarm optimization algorithm, chaotic perturbation is injected to break the local optimum. After breaking the local optimum, a chaotic sequence is generated using Logistic mapping. The perturbation amplitude is inversely proportional to the fitness value of the current optimal solution, which helps to break the local optimum and explore new search regions.

[0066] When in the iterative state, the search for the global optimal solution is accelerated by optimizing the large parameter space through quantum variational optimization or quantum simulated annealing. During multiple iterations, with the dynamic adjustment of inertial weights, the introduction of chaotic perturbations and the application of quantum rotation gates, the algorithm gradually approaches the optimal solution. When the preset number of iterations is reached, the final optimization result of the quantum particle swarm hybrid optimization debugging model is output.

[0067] Quantum computing heuristic optimization helps find the global optimum or near-optimal solution in a large parameter space. Simulated annealing algorithm avoids local optima by introducing random perturbations and eventually converges to the global optimum. Quantum simulated annealing algorithm utilizes quantum superposition and interference effects in quantum computing, enabling the system to explore multiple solution spaces in parallel, thereby greatly improving the convergence speed.

[0068] This method not only utilizes the efficient optimization capabilities of quantum computing in high-dimensional parameter spaces, but also combines the collective intelligence of particle swarms and the global search capabilities of chaotic perturbation mechanisms, effectively avoiding local optima and accelerating the search for global optima.

[0069] Constructing a database of parameter change trajectories includes:

[0070] Using the total psychological needs of individuals as the output prediction parameters of the LC filter, and individual needs related to physiology, environment, and society as quantum states of inductance, capacitance, and quality factor, respectively, the LC filter identifies the missing conditions, insufficient data, desired conditions, and needs of the subject. Iterative transfer calculations are performed based on knowledge distillation to establish the objective function of the LC filter. The mathematical expression of the objective function is as follows:

This represents the Softmax function, used to convert the model's output into a probability distribution. The weight hyperparameter is determined by the magnitude of the backpropagation gradient of the LC filter;

[0074] The goal of combining the concept of psychological field with knowledge distillation-assisted optimization is to use the concept of psychological field to refer to a space of certain correlations or interactions between tasks and parameters. Through this mapping, we can understand and analyze the similarities and changing trends between different tasks in a high-dimensional parameter space, thereby guiding parameter adjustments.

Furthermore, it can help to quickly find similar debugging cases and parameter trajectories in the past in future debugging tasks, providing a reference for new debugging tasks. The parameter change trajectory database can continuously learn and accumulate to optimize the debugging process.

[0077] The LSTM network uses a variant of the gated recurrent unit, with the input being the initialization parameter set of the historical debugging task, and the output layer predicting the optimal parameter direction for the next iteration stage through the Softmax function;

[0078] Based on the learning results of LSTM networks on historical data, a similarity matching algorithm is used to quickly match similar designs and parameter changes, providing initial guesses for new debugging tasks in iterative calculations. The similarity matching algorithm can reduce debugging time from scratch by finding the closest historical cases.

[0079] By using multimodal mixing, multiple influencing factors can be considered simultaneously, resulting in more comprehensive and efficient debugging parameters.
