| 摘 要： | 为改善永磁同步电机系统动静态性能,提高系统鲁棒性,该文引入了一种新的速度调节方法——基于分数阶微积分的控制策略。相对于整数阶PID控制器,分数阶PIλDμ控制器多了两个可调参数,可以取得更好的控制效果。针对永磁同步电机调速系统,构建了基于分数阶速度反馈的闭环系统。仿真结果表明,分数阶PIλDμ控制器的控制效果明显优于整数阶控制器,分数阶控制器的控制系统频率特性优良,在系统负载突变时具有较好的鲁棒稳定性。

| Abstract: | Permanent magnet synchronous motor(PMSM) is a multivariable nonlinear system with strong coupling.It is sensitive to the load and parameter disturbances.In order to improve the robustness of this system,a fractional calculus control strategy is applied to the PMSM drive system.Compared with integer order proportional-integral-derivative(PID) controllers,the fractional order PID controllers are expected that better control performance can be achieved due to the extra tuning knobs.The PMSM speed drive system ... |
