Experimental results: Suboptimal robust linear visual servoing with delay for an underactuated system

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