| 摘 要： | PID算法简单,稳态性能好,但动态性能差.模糊控制方法灵活,适应性强,不依赖于受控对象的数学模型,可以处理系统参数的非线性和不确定性问题,动态性能好,但稳态性能差.为提高双层隔振系统隔离低频结构噪声的不足,将模糊控制理论应用于双层隔振系统,较好地实现了两种算法的结合,弥补了该系统动态性能差的缺陷.仿真结果表明该方法有良好的减振效果.

| Abstract: | The arithmetic of PID is simple and the stability of it is good, but the dynamic characteristic of PID control is poor. The fuzzy logic control method is flexible and adaptable. It does not rely on the model of the system and can deal with the nonlinearity of parameters and uncertain problems. How-(ever,) the stability of fuzzy logic control is poor. The fuzzy control theory combined with PID control is applied to the two-stage vibration isolation system to improve the vibration isolation effect in the low-frequency domain.Simulation results show that the method is effective. |
