The problems of optimal control for sampled-data systems with time-delays and applications in active suspension vibration systems are considered. The optimal control law is derived from a Riccati equation and a Stein equation. The feedforward control and control memory terms compensate for the effects of disturbance and actuator delay, respectively. An observer is constructed to make controller physically...
The problem of optimal vibration for time-delay systems is considered. The delayed system is transformed into a non delayed one by using functional transformations. The optimal control law consisting of state feedback and feedforward compensator is derived from a Riccati equation and a Sylvester equation. The feedforward control compensates for the effect of road vibration. A control memory term is...
