Improved Finite Control Set Model Predictive Speed Control for Permanent Magnet Synchronous Motor
摘要
Abstract
In the traditional finite set model predictive speed control strategy of permanent magnet synchronous motor,the direction of voltage vector is fixed,the range of optional vector is limited,and the sudden change of output voltage leads to large current ripple.Therefore,a direct speed control strategy of finite control set model predictive control(FCS-MPC)based on voltage subdivision is proposed.In the proposed concept,a group of finite voltage subdivision vectors with adjustable amplitude and movable origin are introduced into FCS-MPC scheme as candidate voltages,and bilinear transform(Tustin transform)integral approximation is used to obtain more accurate current prediction.The controller could predict the future current and speed,and uses pulse width modulation to output the optimal subdivision voltage.The simulation results of permanent magnet synchronous motor driven by two-level three-phase inverter show that compared with the traditional FCS-MPC scheme,this method effectively reduces the current ripple,broades the range of voltage vector selection and improves the robustness of the motor.关键词
