In this article, the sliding mode control (SMC) problem is investigated for a class of networked state-saturated systems. In the underlying system, the system states are saturated and unmeasured, and the communication along the sensor-to-controller channel is regulated by the weighted try-once-discard protocol under which only one sensor node is permitted to transmit data at each instant. The key issue of the addressed problem is how to design both the state observer and the observer-based sliding mode controller in the presence of protocol scheduling and state saturation. A token-dependent state-saturated observer is first constructed, and a desired SMC law is then designed with aid of the updating rule for the actually received measurement. Sufficient conditions are established to guarantee both the asymptotic stability of the SMC system and the reachability of the specified sliding surface. The algorithm for acquiring the desired controller gain matrices is proposed in terms of a convex optimization problem. Finally, the effectiveness of the developed observer-based SMC design scheme is verified by a simulation example.

“…[19][20][21] Sliding control theory is a powerful, robust, and high-speed technique to damp any oscillations at the system dynamic performance and to handle nonlinear processed systems. 22,23 Another advantage is the estimation ability to both of system disturbance and states, which enhances considerably the overall dynamic performance under any defined disturbance. 24 ASMC is based on extensive state-observer for more precise and rapid tracking realization.…”

This article presents a novel control technique of Jaya-based super-sliding controller that is applied on superconducting magnetic energy storage system (SCMES). The SCMES will be integrated to operate with tidal turbine generators (TTGs). The penetration of TTGs has recently grown due to distributed generation contributions to the energy sector. To alleviate the potential system instability due to TTG dynamic performance, SCMES is connected to TTG to support the dynamic operational conditions. SCMES is implemented to act quickly during both cases of power generation and absorption, so it can realize any required mismatch between the supply and load power at dynamic transient periods. To enhance such capability, this article proposes the application of Jaya-based super-sliding control technique to control and tune the system dynamic gains. The proposed technique implements incorporated cooperative algorithms using enhanced Jaya competitive algorithm and super-sliding method to facilitate the exchange of energy between the SCMES, the TTG, and the power network. It allows smooth dynamic performance, power quality enhancement, and robust dynamic reference tracking. Jaya-based super-sliding controller is developed and proposed for accurate and reliable control and tunning of system parameters. The proposed controller ensures the superb performance of the synergy of SCMESs and TTGs. Digital simulations have validated the effectiveness of the proposed system with the optimal dynamic parameters and minimization of the global control error.
