Robust Performance and Adaptation Using Receding Horizon H-infinity Control of Time Varying Systems
Receding Horizon H-infinity Control Time Varying Systems
2015/6/19
In this paper we construct suboptimal H-infinity controllers which satisfy a new robust performance condition, using the receding horizon technique. A method is described for the synthesis of H-infini...
