| 摘 要： | 针对永磁同步直线电机中存在非线性、时变性、强耦合性和外部负载不确定性等特点,结合PID控制与模糊控制的优点,将变论域思想引入控制器的设计中,提出一种可变论域自适应模糊PID速度控制策略.该策略解决了在既定规则下无法保证高精度控制的问题,提高了系统的控制性能.仿真结果表明:所提出的控制策略与常规PID控制和模糊PID控制相比,具有更高的控制精度、更快的响应速度和更强的鲁棒性能.

| Abstract: | Focusing on the non-linear,time-varying,strong coupling and external load disturbance existing in PMLSM,a new variable universe fuzzy PID control strategy was proposed.The strategy,absorbing the advantages of PID control and fuzzy control,by introducing variable universe method,has solved the problem of high-precision control in the given rules.Simulation results show that the proposed control strategy has higher precision,faster response and more robustness than conventional PID control and fuzzy PID control. |
