本文以Duffing非线性振子为研究对象 ,应用主动隔振原理 ,设计了参数自调节的PID控制算法 ,对Duffing振子混沌振动进行了主动隔振数值仿真实验 ,实现了对混沌振动的良好隔振。仿真结果表明

In this paper,we study Duffing nonlinear vibration model,using active control isolation principle,propose an adaptive PID controller for controlling Duffing chaotic motion.By adjusting PID response variables online in order to get good isolation results.The simulating demonstrate that active control method can be applied in chaotic vibration isolation.
