摘要
为了实现交流永磁同步电机的高性能速度控制,提出一种能满足系统稳定性和鲁棒性要求的分数阶比例微分控制器。为评价该控制器的性能,将该控制器和采用最优化设计的整数阶比例积分控制器分别应用于同一系统进行了仿真和原型实验。结果表明:采用文中提出的分数阶比例微分控制器的系统响应速度、跟随性能和节能效果均优于采用整数阶比例积分控制器的系统。
In order to implement the high-efficiency velocity control of AC permanent magnet synchronous motors, a fractional-order PD controller satisfying the system stability and robustness is proposed. Then, for the purpose of evaluating the performance of the controller, a comparison between the designed controller and the conventional optimal integer-order PI controller is made via simulations and prototype experiments. The results show that the designed fractional-order PD controller outperforms the optimal integer-order PI controller in response speed and tracking performance, and energy-saving efficiency.
