基于模糊逻辑的混合型电机速度控制器

A Hybrid Motor Speed Controller Based on Fuzzy Logic

模糊控制是一种有效的电机智能控制技术，但没有简单直观的设计方法。本文利用模糊逻辑，把直观的电机控制经验直接转化为公式化的控制规律，根据控制量的特征信息直接确定模糊控制器结构，避免了烦琐的模糊控制器设计过程。由于根据参数和负载变化特征进行模糊补偿控制，系统调速性能好并具有较强的抗参数变化和负载扰动能力。

The fuzzy control is an effective motor intelligent control technique,but there is no simple and intuitive design method.In this paper,the intuitive control experience for motor control is directly transformed into formulated control laws by using a fuzzy method,the structure of the fuzzy controller is determined according to the feature data of the control signal,so the design of the fuzzy controller is very easy.Because the fuzzy compensation controls,which are based on the parameter and load's changes,are used,the performance of variable speed system is very good and the system is robust to the parameter changes and the load disturbance.
