The performance of systems that exhibit repetitive disturbances can be significantly improved using repetitive control. If the repetitive disturbance is periodic with respect to time, perfect asymptotic disturbance rejection can be achieved by well known methods. However, many systems have a repetitive nature with respect to a variable other than time. For this type of systems, we propose a del...

This paper develops a fault-tolerant variable sampling control (VSC) scheme for a class of nonlinear networked control systems (NCSs) with time-varying state and random network delays. An uncertain continuous Takagi–Sugeno (T–S) fuzzy system with both state and input varying delays, in the presence of possible actuator faults, is obtained equivalently on the basis of the input delay methodology...

Traffic prediction systems can play an essential role in intelligent transportation systems (ITS). Prediction and patterns comprehensibility of traffic characteristic parameters such as average speed, flow, and travel time could be beneficiary both in advanced traveler information systems (ATIS) and in ITS traffic control systems. However, due to their complex nonlinear patterns, these systems ...

This paper investigates the problems of asymptotic and robust stability for large-scale discrete state-delayed systems. By means of discrete-type sum inequality approach, an augmented Lyapunov-Krasovskii functional and discrete-type singular model transformation strategy, a new delay-dependent criterion is derived in order to guarantee the robust stability of the above systems. The proposed sta...

We provide a new class of finite-time observers for continuous-time nonlinear systems that are affine in the unmeasured state variable and also contain unknown constant parameters. Our method provides exact values variables parameters, fixed finite time is independent initial values. analogs where there known delay measurements, discrete-time systems. approach does not rely on an adaptive contr...

This paper investigates the robust ∞ H sliding mode control problem for a class of uncertain switched delay systems. A single sliding surface is constructed such that the reduced-order equivalent sliding motion restricted to the sliding surface is completely invariant to all admissible uncertainties. For cases of known delay and unknown delay, the existence conditions of the sliding surface are...

This paper presents an asymptotic state observer for the class of nonlinear dynamic systems with time-delay both in the dynamic equation and in the output equation. In previous works state observers have been studied only for nonlinear systems with delay in the state equation and without delay in the output equation and for nonlinear system with only output delay. Su±cient conditions are given ...
