基于四维开关表的电压源逆变器-永磁同步电机直接转矩控制

In this paper, a direct torque control using a four-dimensional switching-table (4D-ST) is proposed for the voltage source inverter–permanent magnet synchronous motor drive system. The proposed strategy takes a number of virtual vectors, of which magnitude and angle can be configured freely, as candidate vectors. By taking advantage of the variety of the virtual vector, the proposed strategy can o...
