摘要: 为了解决传统滑模观测器算法的滑模面设计中,由于切换控制增益不适配以及开关函数的使用而导致系统高频抖振,进而造成系统观测精度不足的问题,本文以互补滑模控制理论为基础,提出了基于互补滑模的改进观测器,并通过李亚普诺夫函数证明了其稳定性。 针对传统正交锁相环动态跟踪效果较差这一问题,在锁相环环节设计了一种基于增广滑模方法的改进锁相环,进一步提高了系统对转速及转子位置的估计性能。 通过仿真与实验对比验证了所提出的改进算法估计精度更高,动态性能更优。

Abstract: In order to solve the problem of high-frequency chattering caused by switching control gain mismatch and the use of switching function in the sliding mode surface design of the traditional sliding mode observer algorithm,this paper proposes an improved observer based on complementary sliding mode control theory, and proves its stability by Lyapunov function. In addition,aiming at the problem that the dynamic tracking effect of the traditional orthogonal phase-locked loop is poor,an improved phase-locked loop based on the augmented sliding mode method is designed in the phase-locked loop,which further improves the estimation performance of the system for speed and rotor position. Both simulation and experimental outcomes demonstrate enhanced estimation accuracy and superior dynamic performance of the refined algorithm.
