Description: In this paper, a comparison is made between different
implementations of the three-level torque comparator
for a Direct Torque Control (DTC) based induction motor
drive. The DTC scheme controls stator flux and torque by
means of hysteresis comparators, respectively a two-level control
structure for the stator flux and a three-level comparator for
the electromagnetic torque. The standard three-level hysteresis
controller has a DC offset torque error. In this paper, an
additive implementation is investigated in order to remove this
DC offset error. The operational principles of the different
implementations are compared based on continuous and discrete
simulation results, which demonstrate the additional advantages
of the additive structure in a discrete implementation of the
control scheme. Platform: |

Description: 具有梯形反电动势的永磁同步电动机通常被称为无刷直流电动机，它具有结构简单、体积小、重量轻、效率高、高功率密度、启动扭矩大、惯量小和响应快等其它种类直流电机无法比拟的特性。采用电子换向器替代了传统直流电动机的机械换向装置，从而克服了电刷和换向器所引起的噪声、火花、电磁干扰、寿命短等一系列弊病。-With a trapezoidal back-EMF permanent magnet synchronous motor is often referred to as brushless DC motor, it has a simple structure, small size, light weight, high efficiency, high power density, starting torque, inertia, and other types of fast response dc can not match the characteristics of the motor. Electronic commutator DC motor instead of the traditional mechanical reversing device, thereby overcoming the brushes and commutator caused by noise, sparks, electromagnetic interference, short life and a series of ills.

Description: 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.)
