Abstract :
In this paper, the quantized state feedback H∞ control problem for discrete-time linear time-invariant (LTI) systems is studied. The quantizers considered here are dynamic and time-varying. Firstly, taking quantization errors into account, a state feedback controller is designed. Then, by using the designed controller, a state-dependent control strategy is proposed with updating quantizer´s parameter, such that the quantized closed-loop system is asymptotically stable and a prescribed H∞. performance is achieved. An example is presented to illustrate the effectiveness of the control strategy.
