摘要
首先介绍了异步电动机的动态数学模型和矢量控制基本思想;在Matlab/Simulink的环境下分别建立了基于转子磁场定向及电流滞环调节和基于双闭环控制器及S函数的转差型矢量控制系统的仿真模型。两个模型的仿真结果表明,两个系统均具有较好的动、静态性能,适用于各种要求和容量的调速装置,验证了用S函数进行仿真建模方法的通用性和有效性。
Firstly, introduced the dynamic mechanical model of asynchronous motor and the principle of vector control. In the Matlab/Simulink environment, built the simulation models of slip frequency vector control system based on the rotor field-oriented and current hysteresis band control scheme or doubleclosed-loops control scheme with S-function respectively. The simulation results show that both these two models have good dynamic and static performance, and may be applied to speed-adjusting systems with various requirement and capacity. The versatility and effectiveness of simulation modeling method by using S-function is also verified.
