✦ Synopsis

Numerical and experimental investigations on active vibration isolation system are presented in this paper. Two con"gurations are implemented for a statically balanced three-mount system. To reduce the in#uence of payload dynamics and coupling among the control actuators, intermediate masses are added to the system. Linear quadratic Gaussian control and -synthesis are employed in the controller synthesis. The controllers are implemented on the platform of a #oating-point digital signal processor. The results obtained from simulations and experiments indicated that the optimal controllers achieved the desired performance under the constraint of robust stability.

A quadratic programming algorithm is presented for studying the design tradeoffs of active-passive vibration isolation systems. The novelty of the technique is that the optimal control problem is posed as a quadratic optimization with linear constraints. The quadratic cost function represents the me
