最优模糊控制在悬臂梁振动控制系统中的研究

摘要

Based on the vibration control methods of fuzzy control, the corresponding vibration method is analyzed for a vibration system.Signals collected from sensors are calculated by optimal control theory to get theoretical output, which are corresponding with the related system input values.Then creat the fuzzy control rule table containing the optimal solution, and apply it to the actuator in the online processing of the vibration input signal and output optimal control signal.It gets a corresponding execution to suppress the vibration of the cantilever, so as to achieve the goal of vibration control.%基于模糊控制的振动控制方法,针对振动系统,分析了一种振动控制方法,通过传感器将信号采集进来,由最优控制理论离线计算得到理论输出值,并将理论输出值与对应的系统输入值对应起来,从而建立拥有最优解的模糊控制规则表,并在线处理振动输入信号和输出最优的控制信号作用于执行器,产生相应的执行力来抑制悬臂梁的振动,从而达到振动控制的目的.
