基于MRAS参数辨识的PMSM无速度传感器控制
Sensorless Control of PMSM Based on Parameter Identification MRAS
摘要
Abstract
The parameter identification system of permanent magnet synchronous motor based on MRAS under the condition of speed sensorless control was studied. In order to address the problem of deficient-rank in multi-parameter on-line identification. A two-step method that fixes part of the parameters to estimates motor speed, stator resistance and permanent magnet flux was proposed. The parameter adaptive laws were derived respectively in order to ensure the convergence and uniqueness of the parameter estimation. The simulation results showed that the control system could accurately track the speed of the rotor under the load transient change, and has good robustness, with reduced sensitivity on the parameters.关键词
