摘要
Direct predictive current control (DPCC) of permanent magnet synchronous motor (PMSM) is studied. To achieve high-performance operation of PMSM, high-performance current control is necessary. The classical AC motor control methods, such as field oriented control (FOC) and direct torque control (DTC), control stator current indirectly, while FOC with current decoupling and DTC with torque and flux. In this paper, direct predictive current control is studied. Firstly, continuous and discrete state-space equations are deduced. And inverter model is also set up. Secondly, fundamentals and schemes of DPCC are discussed in details. Cost functions are introduced. Finally, simulations of DPCC and FOC are carried out. The simulation results validate the feasibility and efficiency of DPCC.
