文中分析了悬臂梁的振动情况，建立了悬臂梁的动力学系统方程，设计了基于最优模糊控制算法的悬臂梁振动控制系统。系统将采集进来的信号通过最优控制理论计算得到理论输出值，建立拥有最优解的模糊控制规则，使得一个输入得到一个最优的控制输出，从而产生相应的抑制力来减弱梁的振动。使用Matlab对振动控制系统进行了仿真，结果表明该算法能够很好地抑制悬臂梁的振动。%This paper analyzed the vibration of the cantilever, established the dynamic equations of a cantilever system, and designed the cantilever vibration control system based on fuzzy optimal control algorithm. The system calculated the collected signal into the output value by the theory of optimal control theory, and then the optimal solution fuzzy control rules were established by the output value. The system made the input into an optimal control output, resulting in a corresponding decrease vibration suppression force to the beam. Vibration control system using Matlab simulation results show that the algorithm can suppress vibration of the cantilever.
