摘要
针对传统的交流电机参数获取方法存在一定的缺陷,导致矢量控制系统不能实时准确地获取电机的参数的缺点,提出了利用遗传算法辨识电机参数的无速度传感器异步电机矢量控制系统。搭建了实验系统,并进行了相关实验,结果表明该矢量控制系统在启动、调速、稳态运行时具有良好的静、动态性能,表明将遗传算法参数辨识运用到交流电机矢量控制系统能大大提升系统性能。
As the traditional method to obtain AC motor parameters has some flaws,it causes that the vector control system can not accurately obtain motor parameters.The vector control system for speed-sensorless induction motor which run genetic algorithm to identify motor parameters was proposed.The experimental simulation system was set up and the experimental results showed that the vector control system run with good static and dynamic performance at time of its starting,speed regulating and steady-state operating,and genetic algorithm parameter identification being applied to the AC motor vector control system could greatly enhance system performances.
