【摘要】 为了进一步优化解决直接转矩控制系统中的变参数非线性问题,提出了一种适用于异步电动机直接转矩控制的模糊参数P I自适应控制方法,其模糊控制规则的生成是通过分析并优化P I控制的阶跃响应并且结合专家经验而获得的,以此来对电机速度P I调节器进行模糊工作,达到在线调节P I参数的目的,仿真的结果表明了此种设计方法是有效的。更多还原

【Abstract】 In order to further solve nonlinera problem of variation parameters in direct totrque control system,the paper proposes a fuzzy parameter PI adaptive control method which is suitable for the direct torque control of an asynchronous motor.The genaration of its fuzzy control is obtained by analyzing and optimizing PI control step response and combining expert′s experience.For this reason,it carries out fuzzy work to PI regulator of motor speed to achieve to regulate PI parameters on-line.The result of simulation shows that the design is effective.更多还原
