An investigation of active vibration controller for single degree of freedom and multiple degrees of freedom isolation platforms is presented. Three active vibration control techniques are implemented and compared. Apart from adaptive feedforward and feedback control systems, a hybrid controller is proposed which is a combination of the adaptive control with filtered-x least mean squares algorithm and linear quadratic Gaussian state feedback theory for obtaining robust performance and fast convergence. The control plants are identified by frequency-domain technique and implemented on a digital signal processor. Experiments are carried out to evaluate the proposed controller performance at isolation platforms.
