摘要
主要研究的是基于矢量控制的转速/磁链双闭环控制对三相交流异步电机进行调速,系统通过交-直-交变频为电机提供三相交流电源。首先对电机的数学模型进行了分析,并在此基础上建立了基于MATLAB/SIMULINK的模块化仿真模型。该系统采用双闭环控制,分别是速度环和电流环。根据仿真结果可看出该方法是可行有效的,这可为电机控制的实际设计提供很好的思想。
This paper uses vector control and closed-loop control of speed / linkage for adjust the speed of three-phase AC asynchronous motor. The system provides three-phase AC power for motor by use the method of AC- DC-AC conversion. Firstly,the mathematical model of the motor is analyzed,and on this basis,a simulation model based on the MATLAB / SIMULINK is building. The system uses a pair of closed-loop control,namely,speed loop and current loop. And it shows this approach is feasible according to the simulation results,or this can guides a good thinking direction for the design of practical motor control systems.
