Simulation of IPM motor with current vector control drive and DTC drive by nonlinear magnetic circuit model

Interior Permanent Magnet (IPM) motor has high efficiency and large torque because the motor utilizes both magnet torque and reluctance torque depending on magnetic saliency. Most common methods used in control of IPM motor are current vector control and Direct Torque Control (DTC). However, it is too difficult to simulation these control methods including nonlinearity and space harmonics. In this paper, current control and DTC of IPM motor including nonlinear model considering space harmonics is presented and simulated.
