PMSM Current Ripple Suppression Method Based on Mixing Control Set Model Predictive Control
摘要
Abstract
In recent years,model predictive control technology (MPC) widely used in the high dynamic performance of motor drive system,in order to overcome the traditional MPC technology limited control set (FCS) steady current pulsation problem,a kind of based on mixing control set (MCS) predictive control method of all-digital fuzzy current ripple suppression was put forward.First of all,the analysis of discrete mathematics model all-digital fuzzy predictive control system,and the precision of voltage vector and the correlation between current ripple was analyzed.On this basis,the MCS-MPC would voltage source inverter limited number of effective voltage vector,extended to multiple compared with the form of virtual voltage vector,and based on the above online virtual voltage vector to complete the MPC optimization problem;In addition,considering the MCS-MPC system parameter sensitivity problem,analyzed the MCS-MPC system feedback noise problems were discussed.Finally,set up double 15 kW permanent magnet synchronous motor for prototype test platform for experimental analysis,content analysis including the MCS method of dynamic characteristics,current ripple effect of the steady state.The experimental results showed that the proposed MCS-MPC method in retained the traditional predictive control technology,on the basis of high dynamic response,which could effectively reduce the noise of all-digital fuzzy steady current pulsation and operation.关键词
