针对柔性结构在不同激振信号下的振动抑制问题，研究了如何应用模糊控制理论实现柔性结构的主动控制，提出了一种基于连续模糊判决函数的模糊ＰＤ主动振动控制方法，对悬臂梁分别在瞬态、正弦及随机激振下的模糊ＰＤ主动振动控制进行了仿真研究。结果表明：模糊ＰＤ控制对上述三种激振信号的振动均有明显的抑制作用。由于模糊ＰＤ主动振动控制对结构的不依赖性，该方法对难以建模的大型柔性结构的主动振动控制具有实际意义。
Aiming at the problem of vibration suppression of flexible structures under different excitation signals, the paper studies how to apply fuzzy control theory to realize the active control of flexible structures. A fuzzy PD active vibration control method based on continuous fuzzy decision functions is proposed. Transient, sinusoidal and stochastic excitation of fuzzy PD active vibration control were simulated. The results show that the fuzzy PD control has a significant inhibitory effect on the vibration of the above three kinds of excitation signals. Due to the structural independence of fuzzy PD active vibration control, this method is of practical significance for the active vibration control of large flexible structures that are difficult to model.
