摘要 建立了以空气弹簧作为被动隔振元件、超磁致伸缩致动器作为主动隔振元件的精密隔振平台隔振系统,应用LQG控制算法设计其主动控制器。采用MATLAB软件进行了仿真分析以验证系统的振动控制效果。仿真结果表明所设计的振动主动控制系统可在非常宽的频率范围对基础干扰和由仪器设备产生的直接干扰所引起的精密隔振平台振动进行有效的控制。 A hybrid vibration isolation system of precision isolation platform is developed. This system uses air springs as passive vibration isolation elements and giant magnetostrictive actuators as active vibration isolation elements. The active vibration control system is designed according to the LQG control theory. The Matlab is used for simulation of the system. The simulation results show that the developed active vibration control system has good isolation performance against the floor disturbance and the direct disturbance over wide frequency area.
