投影混沌同步试验研究

Experimental study on projective synchronization to a vibration isolation system

针对混沌线谱控制技术遇到的如何在变工况和小振幅条件下实现持续混沌的难题,在理论研究的基础上,根据工程实际,设计了试验台架、线性隔振元件和混沌驱动器,对投影同步进行了试验研究。结果表明,该方法能够使隔振系统在变工况和小振幅条件下稳定地产生混沌响应,控制器具有较强的鲁棒性,因而利用混沌同步降低辐射线谱幅度是可行的。

In order to overcome two difficulties,i.e.,how to maintain a chaotic motion and how to obtain chaos under small amplitude in a varying operation condition arising from practical implements of chaotifying technique for line spectra reduction.A test rack,linear isolation elements and a chaos driving system were designed according to engineering reality,and a test was conducted to validate the efficiency of projective synchronization.The results showed that this method can overcome the above difficulties and reduce radiation line spectra effectively.
