Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] like Figure 1 As shown, the present invention provides an intelligent anti-interference wireless charging school bus control system based on AI large model analysis, including:

[0065] A wireless charging control unit is configured to include a primary circuit, a secondary circuit and a constant voltage filter cascade auto-disturbance rejection control strategy, and a constant voltage filter cascade auto-disturbance rejection control (FCLADRC) strategy is used to wirelessly charge a school bus, wherein the constant voltage filter cascade auto-disturbance rejection control (FCLADRC) strategy includes a first-stage auto-disturbance rejection controller, a second-stage auto-disturbance rejection controller and a Butterworth filter.

[0066] The primary circuit receives AC power and converts it into high-frequency AC power. The high-frequency AC power generates an alternating magnetic field through the primary coil. After the secondary circuit receives the induced AC power, it converts it into DC power through the rectifier circuit. The rectified and filtered DC power passes through the DC-DC conversion circuit to adjust the voltage to the level required by the school bus. The adjusted DC power is used to power the school bus battery or motor system through the constant voltage filter cascade self-disturbance rejection control strategy.

[0067] The constant voltage filter cascade self-anti-disturbance control system of the present application can not only improve the charging response time of the system, but also effectively suppress external interference. When the rated voltage changes, it can also restore the set voltage more quickly. The school bus can be wirelessly charged when it reaches the designated location. The wireless charging is sufficient to meet the operation of the school bus. At the same time, the electric energy received by the wireless charging can also supply the operation of the school bus card swiping system.

[0071] The Butterworth filter, the first-stage ADRC, the second-stage ADRC and the secondary-side DC-DC circuit are combined into a new composite cascade system to obtain a constant voltage filter cascade ADRC control strategy.

[0072] The first-stage anti-disturbance controller receives the secondary output voltage processed by the Butterworth filter and generates a control signal to adjust the primary circuit parameters. The second-stage anti-disturbance controller receives the output voltage of the DC-DC circuit and generates a control signal to adjust the DC-DC circuit parameters. The Butterworth filter is used to filter out the high-frequency noise of the secondary circuit to enhance the anti-interference ability.

[0073] It can be understood that the constant voltage filter cascade self-disturbance rejection control of the present application not only filters the system output ripple, but also solves the amplitude and phase loss caused by the use of filters, effectively improving various aspects of the control system performance.

[0074] By utilizing the constant voltage filter cascade self-anti-disturbance control strategy to monitor the input voltage, output voltage, charging current and other parameters in real time, the parameters of the primary and secondary circuits are dynamically adjusted according to the monitoring results to ensure the stability of the output voltage and provide a constant and reliable charging voltage for the school bus.

[0086] like Figure 2 As shown, Figure 2 The first-stage ADRC also includes a linear tracking differentiator (LTD) and a linear state error feedback (LSEF). LTD is used to generate a smooth reference signal. LSEF uses the output of LESO to calculate the control law. The control signal is normalized by 1 / b_0 and acts on the controlled object. At the same time, the external disturbance also acts on the controlled object, so that the first-stage ADRC can estimate and compensate for the disturbance in real time, thereby improving the anti-interference ability and control accuracy of the system.

[0091] It can be understood that the second control rate generator is the same as the first control rate generator, and thus will not be described in detail.

[0136] S4, collect school bus operation data in real time, and transmit the school bus operation data to the central data processing platform for data processing;

[0137] S5. Perform multi-dimensional analysis on the processed school bus operation data based on the AI ​​big model and generate intelligent scheduling strategies;

[0138] S6, transmitting the intelligent dispatching strategy and the processed school bus operation data to the mobile terminal, and the operator conducts real-time query and use through the mobile terminal;

[0139] S7. Transmit the intelligent scheduling strategy to the school bus driver, and the school bus driver allocates resources according to the intelligent scheduling strategy.

[0140] It can be understood that the user layer collects the school bus operation data in the school bus card swiping system and sends it to the data center for data processing. The data center accepts the scheduled tasks sent by the scheduled task layer, and inputs the processed data into the AI ​​big model for training to obtain the trained AI big model and data analysis results. Users access and process data through the mini program, access the data analysis results of the data center, and determine the school bus usage based on the data analysis results.

[0141] like Figure 6 As shown, in one embodiment of the present application, four control methods are set, namely: first-order filtering LADRC control (F1-LADRC), second-order filtering LADRC control (F2-LADRC), first-order FCLADRC control (F1-CLADRC), and second-order FCLADRC control (F2-CLADRC):

[0142] The time taken for the startup process to reach the set value is 11.35ms, 10.24ms, 8.9ms, and 7.5ms for the four control strategies from high to low, namely F2-LADRC control, F1-LADRC control, F2-CLADRC control, and F1-CLADRC control. It can be seen that the constant voltage filter cascaded anti-disturbance control proposed in this application can effectively improve the response speed, but due to the increase in the filter order, the second-order controller is inferior to the first-order controller;

[0143] When the input voltage suddenly changes, the time it takes for the system to return to a steady state is shown in the following four control strategies: F2-LADRC control, F1-LADRC control, F2-CLADRC control, and F1-CLADRC control. It can be seen that the constant voltage filter cascaded anti-disturbance control applied can solve the problem of sudden input changes and reduce the time it takes for the system to return to a steady state. However, due to the increase in order, the system regulation becomes more complicated, resulting in a worse effect.

[0144] Faced with a sudden load change from 20 to 10. For the time it takes for the system to return to steady state, the four control strategies are F1-LADRC control, F2-LADRC control, F1-CLADRC control, and F2-CLADRC control from high to low. For the overshoot of the system, the four control strategies are F1-LADRC control, F2-LADRC control, F1-CLADRC control, and F2-CLADRC control from large to small. It can be seen that the constant voltage filter cascade self-anti-disturbance control of the present application can solve the problem of load mutation very well, among which the higher order has stronger anti-mutation ability than the lower order;

[0145] When the system faces an external step disturbance. For the time taken for the system to return to steady state, the four control strategies are F2-LADRC control, F1-LADRC control, F2-CLADRC control, and F1-CLADRC control from high to low. For the overshoot of the system, the four control strategies are F1-LADRC control, F2-LADRC control, F1-CLADRC control, and F2-CLADRC control from large to small. It can be seen that the constant voltage filter cascade self-anti-disturbance control of the present application can solve the problem of external disturbance very well, which verifies the effectiveness of the proposed strategy, in which the overshoot of a higher order is smaller than that of a lower order, and the time taken for a lower order to return to steady state is shorter than that of a higher order.
