【摘要】 给出了一种基于自适应遗传整定PID(AGT-PID)控制算法的无线充电系统控制策略，在MATLABSimulink中完成了整个系统的仿真，并基于FPGA完成无线充电系统的测试。当调节信号下达时，AGT-PID控制器将处理后的输出电压值与目标调节值进行对比并对误差值进行遗传迭代。AGT-PID控制器通过对目标函数权值的自适应调整得到适应度函数，完成PID参数的自适应整定，最终提升了无线充电系统的控制稳定性及控制精度。验证结果表明:当调节信号下达后，所提出的控制方法能够满足无线充电系统的功率需求，建立时间少于2 ms，超调小于4%，稳态误差低于1%，满足无线充电系统的设计规格和稳态性能要求。更多还原

【Abstract】 A wireless charging system control strategy based on adaptive genetic tuning PID( AGT-PID) control algorithm is proposed.The simulation of the whole system in MATLAB Simulink,and the wireless charging system test based on FPGA are completed. When the regulation signal is released,the AGT-PID controller compares the processed output voltage value with the target regulation value and carries out genetic iteration on the error value. The AGT-PID controller obtains the fitness function through the adaptive adjustment of the weight of the objective function,completes the adaptive tuning of PID parameters,and finally improves the control stability and control precision of the wireless charging system. The verification results show that the proposed control method can meet the power requirements of the wireless charging system with the establishment time being less than 2 ms,the overshot being less than 4%,and the steady-state error being less than 1%.更多还原
