基于拉萨尔不变集定理控制同步磁阻电动机的混沌振荡

摘要

A new strategy for chaos control was investigated using the LaSalle's invariant theory. This strategy was free of the effect of uncertain equilibria in the synchronous reluctance motor. The accuracy and validity of the proposed control method were approved by the results of simulation analysis. The strategy can automatically find the balance point of the system and work when the motor balance point is unknown, so the principle is simple, direct and favorable to practical application. The study results are helpful for maintaining the secure operation of synchronous reluctance motor.%首先基于拉萨尔(LaSalle)不变集定理提出一种新的控制方法,然后证明混沌同步磁阻电动机(Syn-RMs)在该控制器作用下达到稳定.由于该控制方法能自动识别系统平衡点,在电机平衡点位置未知的情况下仍然有效,因此控制器设计原理简洁直接,有利于实际应用.研究结果对保证SynRMs的可靠运行具有重要意义.
