摘要
为解决传统基于滑模观测器永磁同步电机无位置传感器控制系统存在的抖振问题,本文提出了一种基于非线性能量函数参考模型的新型改进滑模观测器。在分析非线性能量函数参考模型的基础上,设计了改进的滑模观测器,建立了PMSM基于改进滑模观测器的无位置传感器控制系统的数学模型。同时应用Simulink仿真试验平台,验证了PMSM基于改进滑模观测器无位置传感器控制的可行性。
To solve the chattering problem of traditional sliding mode observer in the permanent magnet synchronous motor( PMSM) sensorless vector control system,this paper proposed a new improved sliding mode observer based on a non-linear energy function reference model. On the basis of the analysis of non-linear energy function reference model,an improved sliding mode observer was designed,and the model of PMSM sensorless vector control system based on the improved sliding mode observer was established. At the same time using simulink simulation platform,the simulation test has proved the feasibility of the improved sliding mode observer based sensorless vector control system.
