模糊自适应PID控制器在交流伺服控制系统中的研究

The research of fuzzy self adaptive PID controller in AC servo control system

交流伺服控制系统中的永磁同步电机是一种多变量、强耦合和非线性的系统,采用传统的PID控制难以达到较好的控制效果。将模糊自适应PID应用于永磁同步电机的控制中,运用模糊控制原理对PID参数进行整定。仿真结果表明,与传统的PID控制相比较,采用模糊自适应PID控制器的交流伺服控制系统具有更好的动态和稳态性能,实现了较好的控制效果。

The permanent magnet synchronous motor in AC servo system is a kind of multivariable, strong coupling and nonlinear control system,so it is difficult to achieve a good control effect by a traditional PID control. In this paper, we apply fuzzy self adaptive PID to permanent magnet synchronous motor controller, and use the fuzzy control principle to make PID parameters deposition. The simulation results show that, comparing with the traditional PID control, AC servo control system by adopting Fuzzy Self Adaptive PID controller has a more static and dynamic performance,and achieves a better control effect.
