基于模糊自整定PI的PMSM伺服系统的仿真研究

Simulation and Research on Servo System of PMSM Based on Fuzzy Self-tuning PI

为了解决永磁同步电机(PMSM)速度控制问题,提出了一种模糊自整定PI的控制方案,并用MATLAB对系统进行了建模仿真验证。仿真实验结果表明,该种新型控制算法与传统的PI控制相比较,具有很强的适应性、鲁棒性和抗干扰性,能快速跟踪设定速度,三相电流与转矩波动较小,并且在改变负载时,能快速恢复到额定状态。

To solve the speed control problem of permanent magnet synchronous motor（PMSM）,this paper proposes a fuzzy self-tuning PI control scheme,and uses MATLAB to system-modeling.Simulation experimental results show that the new control algorithm has very strong adaptability,robustness and anti-interference,compared with the traditional PI control,it can quickly track the set speed,due to three phase current and the small torque ripple,when changing the load,it can quickly recover to the rated condition.
