基于模糊理论的自适应控制器在直接转矩控制系统中的应用

Application of Self-adaptive Controller Based on Fuzzy Theory in Direct Torque Control System

采用一种基于模糊理论的自适应控制器作为直接转矩控制系统的速度调节器,该控制器由常规PID控制部分和模糊推理两部分组成,通过模糊推理实现常规PID控制器参数的实时优化调整,从而实现速度环的自适应控制,有效地提高了系统响应速度。

This paper introduces a self-adaptive controlle r based on fuzzy theory which is used as the speed controller in direct torque c ontrol system. The controller is made up of traditional PID and fuzzy inference. The parameters of the traditional PID are adjusted by fuzzy inference in real - time so that it can come to self-adaptive controlling of speed.
