This paper studies the problem of actuator-nonlinearities compensation in the multi-input uncertain neutral systems. The neutral systems with different unknown time-varying delays, unmodeled dynamics, nonlinear perturbations and disturbances are considered. A new methodology based on the online estimation of the delays to compensate for the effects generated by dead-zone and saturation, acting in...
In this paper, the stabilization problem of actuators saturation in uncertain chaotic systems is investigated via an adaptive PID control method. The PID control parameters are auto-tuned adaptively via adaptive control laws. A multi-level augmented error is designed to account for the extra terms appearing due to the use of PID and saturation. The proposed control technique uses both the state-feedback...
In this paper, adaptive state feedback actuator failure compensator for networked control systems (NCSs) with state dependent disturbances are developed. The obstacles of NCSs such as; transmission delays and data-packets dropout induced by the insertion of data networks in the feedback adaptive control loops are also considered. Adaptive laws are designed for updating the controller parameters. Closed-loop...
In this paper, adaptive state feedback stabilizing controllers for networked adaptive control systems with actuator failures are developed. The problems of networked control systems such as; transmission delays and data-packets dropout induced by the insertion of data networks in the feedback adaptive control loops are also considered. Sufficient conditions for Lyapunov stability are derived in the...
This paper addresses the adaptive stabilization problem of linear networked control systems with network-induced delay in the presence of state-dependent disturbances. The case of state feedback is treated in which a new adaptive model of networked control system in the presence of network-induced delays and state-dependent disturbances is proposed. Based on Lyapunov stability theory, new delay-dependent...
Since data packet losses and network-induced delays might be potential sources to instability and poor performance of networked control systems, the main objective of this paper is to design an adaptive stabilizing controller for networked systems with time-varying network-induced delay and packet loss. With the continuous-time approach, the case of state feedback is studied in which a new adaptive...
