异步电机直接转矩控制系统仿真：
模型整体结构分为三大部分：主电路部分（直流电源、逆变器、电机）、控制系统部分（采用的是直接转矩控制，所以主要有坐标变换模块，灰色部分，磁链观测器模块，红色部分，直接转矩开关表选择模块，蓝色部分，以及外环的转速调节器ASR）剩下的就是仿真结果波形观测部分（观测信号依次向下为定子ab相线电压、三相定子电流、电机转速、电机电磁转矩）
运行初始条件为以1420r./min的额定转速电机空载启动，在0.3s时刻突加额定负载50牛米。在0.5s时刻电机转速突然下降为1200r/min。整个动态过程既可以分析稳态运行波形，又可以分析负载扰动情况下的动态响应和转速扰动情况下的动态响应。(Simulation of induction motor direct torque control system:
Model of the whole structure is divided into three parts: the main circuit part (DC power supply, inverter, motor control system (part), using the direct torque control, so the main coordinate transformation module, flux observer module, gray, red, direct torque switch table selection module, the blue part, and the outer ring of speed regulator ASR) the rest of the results observed (the observation signals are down for the AB phase stator voltage, three-phase stator current, motor speed, motor electromagnetic torque)
The initial conditions for the operation to start the motor no-load rated speed 1420r./min, 50 nm in 0.3s moment of sudden rated load. At 0.5s, the motor speed drops suddenly to 1200r/min. The whole dynamic process can not only analyze the steady state operation waveform, but also analyze the dynamic response under load disturbance and the dynamic response under the condition of speed disturbance.)
