摘要
针对多电飞机机电作动器鲁棒性差、控制精度低的问题,提出了一种基于模糊PID的控制策略。建立了EMA系统的非线性模型,永磁同步电机控制模块采用SVPWM调制技术控制开关驱动。考虑系统参数摄动的影响,加入模糊PID自整定控制器,通过仿真结果和分析表明,该控制策略可有效提高系统控制精度。
Aiming at solving the problem of poor robustness and lowcontrol accuracy of the EMAs of MEA,a control strategy based on fuzzy PID is proposed.The nonlinear model of EMA system is established,and the PMSM control module adopts SVPWM modulation technology to control the switch,and the closed-loop servo control strategy of position,current and speed is designed.Considering the influence of system parameter perturbation,the fuzzy PID self-tuning controller is added.The simulation results and analysis showthat the control strategy can effectively improve the control precision of the system.
