摘要:

为了提高永磁同步电机调速系统的控制性能,克服扰动对转速的影响,研究了一种变指数快速幂次趋近律。该趋近律趋近速度快,抖振小。基于该趋近律设计永磁同步电机积分滑模速度控制器,用李雅普诺夫函数对控制器进行稳定性分析,并与传统指数趋近律控制器、PI控制器进行仿真对比,结果表明采用变指数快速幂次趋近律控制器的系统速度响应快,鲁棒性强,具有良好的动、静态性能。

Abstract:

To improve the control performance of the speed control system and to reduce the influence of disturbance on the speed in the permanent magnet synchronous motor(PMSM), a variable exponential fast power reaching law was studied. The approaching law approaches fast speed and small chattering. The integral sliding mode speed controller of the permanent magnet synchronous motor based on the reaching law was designed, and the Lyapunov stability theory was used to analyze the stability of the controller. The simulation was conducted to compare with the traditional exponential reaching law controller and PI controller, the results show that the system with variable exponential fast power approaching law controller has fast speed response, strong robustness, and good dynamic and static performance.

Key words: variable exponential fast power reaching law, speed response, sliding mode control
