New stability criteria and stabilization methods on networked control systems (NCSs) with short time-varying delay (STVD) are proposed in this paper. An NCS with STVD is transformed into a time-varying discrete time system. And then, this discrete time system is converted into a equivalent time-invariant system with norm-bounded uncertainties by using robust control techniques. Using this method,...
This paper deals with the design problem of optimal robust non-fragile H∞ state feedback controller for networked control systems (NCSs) with uncertain time-delays and controller gain perturbations. First, a new method is presented, according to which the NCS with uncertain time-delays in one sampling period is transformed into a discrete linear system with uncertain parameters. Second, considering...
To overcome the difficulties in the stability analysis and stabilization for nonlinear fractional systems, the comparison principle for fractional-order systems with Caputo fractional derivatives is constructed, which can simplify the processes of stability analysis and stabilization controller design in a great degree. To verify the feasibility of the proposed method, the problem of stabilizing the...
