ANALYSIS AND OPTIMAL DESIGN OF NETWORKED CONTROL SYSTEM WITH VARYING SAMPLING RATE

摘要

This paper focuses on the state observer design for networked control system with short delay and less noise by varying sampling period, where the sampling rate belongs to some known set of time intervals. The static observer gain can be achieved by solving a set of linear matrix inequalities (LMIs). Moreover, the method guarantees that the covariance of the estimation error will be asymptotically bounded by an upper bound, which can be optimized. The simulation results illustrate the effectiveness of the proposed method.
