摘要:

针对传统永磁同步电机滑模控制方法产生抖振现象和外界干扰带来的一些不确定的影响,提出了一种新的模糊滑模控制器设计方法。首先,基于滑模控制和模糊控制两大理论,在转速环引入全局快速终端滑模控制,并设计一种新型复合趋近律,在削弱抖振的同时,又能使系统在有限时间内快速达到稳态;然后以Lyapunov函数导数的绝对值为补偿构建了自适应干扰估计项,对外界干扰进行准确估计,进而设计了全局快速终端模糊滑模控制器,通过仿真对比试验,验证该控制器能快速收敛到稳定状态,而且能够有效地抑制传统滑模控制器的抖振情况,验证了所提方法的有效性。

Abstract:

A new fuzzy sliding mode controller design method for permanent magnet synchronous motor(PMSM) is proposed to solve the problems caused by chattering and external interference. Firstly, based on the two theories of sliding mode control and fuzzy control, global fast terminal sliding mode control is introduced into the speed ring, and a new compound reaching law is designed, which can weaken buffeting and make the system reach steady state quickly in a finite time. Then, the absolute value of the derivative of the Lyapunov function is used as compensation to construct an adaptive interference estimator to accurately estimate the external interference, and then a global fast terminal fuzzy sliding mode controller is designed. Through simulation and comparison experiments, the controller can quickly converge to a stable state and effectively suppress the buffeting of the traditional sliding mode controller, which verifies the effectiveness of the proposed method.

Key words: Permanent magnet synchronous motor, sliding mode control, fuzzy control, new compound reaching law, global fast terminal sliding mode controller circuit breaker
