In this paper, we consider quantizers and controllers design of uncertain interconnected Hinfin decentralized feedback networked systems with two quantized signals in states/outputs and control inputs. We first assume that a decentralized state feedback controller has been designed for an interconnected continuous-time networked system so that the closed-loop system is Hurwitz stable and a desired...
According to the nonlinear closed electro-hydraulic proportional system, a multiple sliding mode adaptive control method is proposed. Recursive technique is used to simplify the control problem of higher-order system. A robust adaptation scheme was used to reduce the tracking error resulted from system uncertainties . Firstly, the recursive technique and state feedback precise linearization scheme...
The issue of robustly exponential stability for uncertain neutral-type systems is considered in this paper. The uncertainties are nonlinear and the discrete-delay is time-varying. In terms of a linear matrix inequality (LMI), the new sufficient stability condition with delay dependence is presented. The model transformation and bounding techniques for cross terms are avoided based on an integral inequality...
