摘要
Active vibration control is widely used in both defence and civil industries and therefore, its principle and design are discussed, and acceleration, velocity and displacement of the mass are used as the input variables for the controller. In practice, the time delay of mechanical system should be taken into consideration. An experiment has been successfully made with a HCM-I ultra-precision turning machine. Experimental results indicate that active vibration control can effectively isolate the vibration from the base, and the vibration transmissibility from base to the machine is distinct descend.
