摘要
将模糊控制算法引入传统PID控制,对双闭环直流调速系统进行了设计和仿真。将操作人员和专家长期实践积累的经验知识用控制规则模型化,模糊推理在线辨识对象特征参数,实现了无须精确确定对象模型就可实时改变控制策略。构建了模糊控制方式的直流电动机双闭环调速系统的模型,在Matlab软件环境中进行了设计和仿真,从输出波形可以看出系统性具有明显改善。
A speed regulation system for DC double closed loop motors is designed and simulated based on combining the fuzzy and PID control algorithms. The practical experiences and knowledge accumulated by experts and skilled operators are modeled with control rules, and the objective characteristic parameters are identified by fuzzy inference on - line. The control strategy may be changed in real time without determining the accurate objective model The model of speed regulation system for DC double closed loop motors is established by the fuzzy control method. The output waveform obtained from MATLAB simulation shows a significant improvement of the system performance.
