Guaranteed Cost Control for Multirate Networked Control Systems with Both Time-Delay and Packet-Dropout

الملخص EN

Compared with traditional networked control systems, the sampling rates of the nodes are not the same in the multirate networked control systems (NCSs).

This paper presents a new stabilization method for multirate NCSs.

A multirate NCSs with simultaneous considering time-delay and packet-dropout is modeled as a time-varying sampling system with time-delay.

The proposed Lyapunov function deceases at each input signal updating point, which is largely ignored in prior works.

Sufficient condition for the stochastic mean-square stability of the multirate NCSs is given, and the cost function value is less than a bound.

Numerical examples are presented to illustrate the effectiveness of the proposed control scheme.
