摘要
本文提出了一种用于永磁同步电机位置伺服系统的自适应模糊滑模控制器(AFSMC)的设计方法,同已有的模糊滑模控制相比,滑模控制律中的等效控制项和切换控制项分别由模糊系统代替。此外,还为模糊规则后件参数设计了在线调节算法,给出了稳定性分析。该方法避免了抖振问题同时保证了鲁棒性。仿真和实验结果表明了此算法的有效性。
This paper presented the design of an adaptive fuzzy sliding mode controller （AFSMC）for PMSMposition servo drive. In contrast to the existing fuzzy sliding mode control, both the equivalent control termand switching-type control term in the sliding mode control law were substituted by fuzzy systems, respectively. Moreover, an on-line adaptive tuning algorithm for the consequent parameters in the fuzzy rules was alsodesigned, the stability analysis for the adaptive control scheme was provided. The chattering effect is attenu-ated and robust performance can be ensured. Simulation and experiment example verify the effectiveness ofthe proposed method.
