摘要

Fuzzy - time varying composite control to rotor vibration with SMA(Shape Memory Alloy) is proposed. Fuzzy control was applied in active control to rotor vibration, and the effect of uncertainty of mechanical model of SMA on system control was avoided; time-varying control was introduced to restrain transient response caused by parameter varying with time in variable stiffness control of rotor system, control discipline was designed by gradient algorithm. The simulation results show that composite control can reduce steady and transient response of system effectively, and vibration amplitude of improved system is only 60% of the original one.
