Abstract:In order to offset the deficiency of passive vibration isolation system of power equipment on submarine, the control system of multi-step predictive self-tuning arithmetic in hybrid vibration isolation system was build. The model of the system was obtained and the design of control system was given. And the same time a example of system design was simulated and analyzed. The result showed that the control system of multi-step predictive self-tuning arithmetic in hybrid vibration isolation system can effectively offset the .deficiency of passive vibration isolation system and the system have the well performance of robust.
