摘　　要：为获取电机制动方式实现的约束条件及制动过程的瞬态特性分析,运用Matlab/Simulink仿真环境平台,应用基于d-q坐标下数学模型建立的电机仿真模型及Simulink工具箱中断路器、阻抗等工具搭建电机制动方式仿真控制模型。通过反复调节模型中模块参数,改变电源电压或负载大小、回路断开闭合的时间等,找到能耗制动、电源反接制动、倒拉反接制动、回馈制动控制回路最优参数,并能直观观察分析比较其制动过程中的定转子瞬态电流、速度及其制动转矩变化的暂态过程,由此确定电机性能为具体的工程案例应用提供实践依据,同时,建立的仿真模型方法也为电机控制运行及其它制动方式建模提供理论指导。In order to get some constrains and transient process of asynchronous motor braking, by Matlab/Simulink environment, and based on motor simulation model of the mathematic model of d-q coordination and breakers and resistors of Simulink tools, simulation controlling model of motor braking is gotten. The simulation result shows that this method can get the optimi- zation parameters of exhausted-braking, reserve-connection braking, regenerative braking through repeatly modifying voltage and resistors parameters, and so on, what＇s more, the transient process alteration of rotator and stator current, rotation speed and retarding torclue is analyzed. Simulink results can guide us for special project application, at the same time, this method of building simulation model also supply theory into practice for building model of control running of motor and other braking model.
