Description: This circuit uses the AC6 block of SimPowerSystems™ library. It models a permanent magnet (PM) synchronous motor drive with a braking chopper for a 3HP motor.
The PM synchronous motor is fed by a PWM voltage source inverter, which is built using a Universal Bridge Block. The speed control loop uses a PI regulator to produce the flux and torque references for the vector control block. The vector control block computes the three reference motor line currents corresponding to the flux and torque references and then feeds the motor with these currents using a three-phase current regulator.

Description: 永磁同步电机直接转矩控制中引入SVPWM技术后，磁链和转矩脉动明显减小,且速度响应明显加快。这是由于传统的DTC系统釆用滞环控制器,每个周期选择一个幵关电压矢量,不能完全补偿转矩和磁链的误差 而后者采用PI控制器和SVPWM调制,可选择多个基本电压矢量来合成任意的电压矢量,能够更好的补偿误差。仿真结果说明,基于SVPWM的DTC系统在磁链幅值响应以及转矩响应上的改善效果很明显。-the impact of space voltage vector of the stator flux and the electromagnetic torque.Secondly, the paper introduces direct torque control of permanent magnet synchronous motor SVPWM technology.Under the same hardware conditions,the system can obtain More continuous voltage space vector by taking advantage of SVPWM.T
