Abstract :
This article synthesized suboptimal control for an underactuated system with delays; it also presents a robust stability dependent to delay. Using dynamic programming, an optimal quadratic regulator (LQR) controller is synthesized, which is then applied to a linear matrix inequality, giving delay-dependent sufficient conditions. This delay is analyzed for both time-invariant case and for time-variant case. We presented an application in Visual Servoing for the inverted pendulum.
