采用模糊控制理论对双层隔振系统进行主动控制仿真.这种策略无需考虑一般自适应前馈控制所引起的次级振源对控制器输入的反馈问题(耦合通道的影响)及次级振源到误差评价传感器之间的传递函数(误差通道)对控制过程的影响,控制系统简单易行.研究结果表明,所采用的模糊控制策略对于周期和随机振动信号均有很好的控制效果.
採用模糊控製理論對雙層隔振繫統進行主動控製倣真.這種策略無需攷慮一般自適應前饋控製所引起的次級振源對控製器輸入的反饋問題(耦閤通道的影響)及次級振源到誤差評價傳感器之間的傳遞函數(誤差通道)對控製過程的影響,控製繫統簡單易行.研究結果錶明,所採用的模糊控製策略對于週期和隨機振動信號均有很好的控製效果.

The fuzzy active vibration control technique is studied in this paper.In this technique, it is not necessary to account for the feedback of minor vibration sources to the controller's input (coupling channel) induced by the adaptive control process and the influence of the transmission function between the minor vibration sources and the error-evaluation sensors (error channel) on the control procedure.Thus, the control system becomes simpler and more feasible.Simulation result verifies that this strategy is effective for periodic and random vibration signals.
