Model Predictive Torque Control with Switching Table for Neutral Point Clamped Three-Level Inverter-Fed Permanent Magnet Synchronous Motor
摘要
Abstract
A model predictive torque control (MPTC) is proposed for a neutral point clamped (NPC) three-level inverter based permanent magnet synchronous motor (PMSM) drive system. The flux and torque components in the cost function are equivalent to the amplitude of the difference between reference voltage vector and the basic voltage vector. By dividing the vector space logically, a predictive switching table is built. The built switching table can select the voltage vector which minimizes the amplitude mentioned above. The selected vector is then used as the output of the second step prediction. Thereby multiple model predictive calculations of the second step prediction are replaced by selecting a vector from switching table. The experimental results show that the improved MPTC strategy controls the flux, torque and neutral point voltage effectively. Compared with the traditional MPTC method, the improved MPTC strategy also has lower computation.关键词
