Abstract :
This paper focuses on a special form of networked control systems (NCSs): model-based NCSs (MB-NCSs). MB-NCSs were proposed in order to reduce the number of data packet exchanges between sensors and controllers/actuators by using linear-time-invariant nominal models and some appropriate coder and decoder algorithms. This paper proposes a new uniform dynamic coding and decoding algorithm for MB-NCSs whose design parameters depend on the choice of the controller for the nominal model, the model mismatch between the nominal model and the plant as well as the sampling period. This new algorithm can ensure that the closed loop stability of MB-NCSs by choosing proper coding and decoding parameters. The robustness of this algorithms with respect to the model mismatch has also been addressed. Simulation results demonstrate the effectiveness of the proposed algorithm.
