Semi-active Fuzzy Control for Vibration Isolation System with Magnetic Suspension isolator
The magnetic suspension isolator is designed. The vibration isolation system supported by magnetic suspension and ordinary vibration isolators series structure and its equivalent model are established. Taking the system as research subject, the dynamic mathematic expression of the system is established. Equivalent stiffness and damping are obtained.Base on the expression, semi-active output feedback mode fuzzy controller is designed for the isolation system. Then, the appropriate current and optimal stiffness of magnetic suspension isolator could be obtained. Under complex-frequency exciting signal and shock exciting signal are simulated. The simulation results indicate that the isolation performance and shock resistance characteristic of magnetic suspension supporting isolation system with semiactive mode fuzzy control method are more effective in vibration isolation in comparison with the passive system.
