Design of Double Loop DC Motor Speed Control System Based on Fuzzy Control and Generic Algorithm

将遗传算法与模糊控制相结合,针对工程上通常采用直流调速系统,详细分析双闭环调速系统的模糊自整定PID控制,设计了模糊控制器并对直流双闭环调速系统进行建模。对系统的转速环的动态性能、抗干扰性能进行仿真分析。最后,与传统PID控制进行比较,得到模糊自整定控制可以大大提高控制效果、抗扰性能强、系统响应速度快、动态性能好等优点。

Some problems are solved in double DC speed regulation by the combination of fuzzy control with generic algorithm.Double close loop DC speed regulation of the fuzzy PID control is illustrated in detail,simulated respectively the characteristics of the dynamics and anti-disturbance of speed loop.Last,Compared with traditional PID control,control effects have been greatly improved by fuzzy control,which characterized by its stronger anti-disturbance,quick response and good dynamics.Simulation showed that the system had no over-tuning overcomed the affects of the changes of loading and the ripple of electrical net voltage, etc.
