Preview control of polytopic time‐varying systems subject to actuator saturation

In this study, a novel method is proposed to track a previewable reference signal in the polytopic time‐varying system with input saturation. Firstly, an augmented model containing future information is constructed using a new formal variable. This leads to the tracking control problem of polytopic...

Summary:In this study, a novel method is proposed to track a previewable reference signal in the polytopic time‐varying system with input saturation. Firstly, an augmented model containing future information is constructed using a new formal variable. This leads to the tracking control problem of polytopic time‐varying system with input saturation is transformed into a stability problem of augmented error system. Next, the state and static output feedback preview controls are introduced, and the corresponding controller gains are produced by the proposed conditions. Two examples are presented to validate the effectiveness of the proposed preview controller.
