基于二阶滑模扰动观测的PMSM电流预测控制研究
Research on PMSM Current Predictive Control Based on Second-order Sliding Mode Disturbance Observation
摘要
Abstract
To address the issue of the dependence of DPCC on motor parameters and the susceptibility of system performance to inductance parameters,a permanent magnet synchronous motor(PMSM)current prediction control method based on second-order sliding mode disturbance observation is studied.Firstly,based on the principle of sliding mode control,the impact of inductance parameter mismatch on the robustness of system parameters is analyzed,as well as the system"chattering"caused by discontinuous functions in traditional sliding mode control;Then,a sliding mode disturbance observer(SMDO)based on second-order convergence law is introduced in DPCC to compensate for disturbances caused by inductance parameter mismatch in real time,while accelerating the convergence of disturbance errors through second-order convergence law;Finally,compare the method with DPCC and SMDO+DPCC through simulation experiments.The experimental results show that in the case of mismatched inductance parameters,this method reduces the steady-state error of current,improves the robustness of system parameters,and reduces the system"chattering"phenomenon caused by traditional sliding mode control.关键词
