An H ∞ LPV design for sampling varying controllers: experimentation with a T inverted pendulum David Robert?, Olivier Sename? and Daniel Simon Abstract—This paper deals with the adaptation of a real-time controller’s sampling period to account for the available computing resource variations. The design of such controllers requires a parameter-dependent discrete-time model of the plant, where the parameter is the sampling period. A polytopic ap-proach for LPV (Linear Parameter Varying) systems is then developed to get an H ∞ sampling period dependent controller. A reduction of the polytope size is here performed which drastically reduces the conservatism of the approach and makes easier the controller implementation. Some experimental results on a T inverted pendulum are provided to show the efficiency of the approach. Index Terms—Digital control, linear parameter varying sys-tems, H ∞ control, real experiments. I
