摘　　要：提出一种在线自组织模糊逻辑控制器的设计 .该设计应用于含压电驱动器柔性结构的振动控制中 ,不需建模 ,可用输入 /输出历史数据生成模糊规则 .将生成的规则存储在模糊规则库中 ,通过自组织过程进行在线更新 .同时对悬臂梁分别在瞬态和正弦激振下的模糊主动控制进行了仿真实验 .结果表明 ,该控制器对上述两种激励的振动比传统模糊控制器有更明显的抑制作用 .Proposed in this paper is the design of an on-line self-organizing fuzzy logic controller (FLC),which is applied to the vibration control of flexible structures containing piezoelectric actuator. In this design,fuzzy rules are generated by using input/output historical data without modeling. The generated rules are stored in the fuzzy rule base and updated on-line by a self-organizing procedure. A simulation experiment of the fuzzy active control of a cantilever beam with transient and sinusoidal vibrations was carried out,thus reaching the conclusion that the proposed controller has more distinct control effect on the two vibrations than conventional FLCs.
