Voltage Vector Rapid Screening-Based Three-Vector Model Predictive Current Control for Permanent Magnet Synchronous Motor
摘要
The permanent magnet synchronous motor's current regulation is predicted using a dual vector model, the current still has a large pulsation because of the limited selection of the second effective vector. To address this issue, discourse provide a voltage vector fast selection based three-vector model predictive current control method for permanent magnet synchronous motors. To cut down on computation and limit control complexity, a quick selection of an efficient voltage vector switching table is created. A voltage vector with an arbitrary direction and amplitude is created by combining the chosen voltage vector with the zero voltage vector. The current ripple is reduced effectively, and the deadbeat control of the direct improves the system's steady-state performance, and quadrature current components simultaneously. The simulation results indicate the validity and usefulness of the proposed technique.
