A Simple and Robust Model Predictive Current Control of PMSM Using Stator Current Predictor and Target-Oriented Cost Function

Model predictive current control of permanent magnet synchronous motor(PMSM), which inherits from the vector framework, has become a promising strategy because its simple structure and fast dynamic response. In order to protect stator prediction model influence mismatched parameters, robust with predictor target-oriented cost function (abbreviated as SCP-TOSF-PCC) is proposed in this paper. The feedback mechanism introduced into equation discrete domain, design principle stability analysis are also described detail. addition, different traditional method constructed by tracking errors current, paper proposes direct function, takes average pulsations d-axis q-axis judge index. account historical values on voltage selection. experimental results show that compared methods, better dynamic, steady-state performance.
