The present invention firstly determines the adjustment parameters to be optimized, draws the adjustment parameters to be optimized from the simulation model to be designed as the input parameters of the simulation model to be designed, converts the engineering constraint requirements of the design simulation model into constraint conditions, and converts the design index requirements into The optimization index of the parameter to be optimized and adjusted, the general optimization algorithm function is called to perform automatic optimization, and the final adjustment result of the parameter to be optimized and adjusted is determined from the data of the automatic optimization process, which is suitable for various applications, such as: flight trajectory The optimization of parameters and controller parameters, and the number of parameters to be optimized and adjusted is not limited, which can help designers improve design efficiency.

Description

technical field [0001] The invention relates to the technical field of algorithm design and simulation, in particular to a parameter optimization and adjustment method and system. Background technique [0002] In the process of designing and simulating the guidance and control system of an aircraft, it usually involves design issues such as flight trajectory planning, flight attitude control and flight center of mass position control. Taking flight trajectory planning and design as an example, the traditional design process is as follows: figure 1 As shown, in the traditional design process, it is necessary to judge whether the simulation results meet the design requirements. If the requirements are not met, it is necessary to return to the previous step, readjust the model parameters, and re-simulate until the simulation results meet the requirements. This traditional multi-parameter optimization adjustment needs to be adjusted manually, and the adjustment process is labor...
