“…Especially to achieve noise suppression and disturbance attenuation, Reference utilized a modified DOBC structure to propose the robust controller. Meanwhile, since the disturbances widely exist in communication networks, many methods have been proposed to study the disturbed NCSs . In Reference , by utilizing robust adaptive sliding mode control, an observer was designed to estimate the disturbance in switching NCSs.…”

INTRODUCTIONNetworked control systems (NCSs) are described as the spatially distributed systems in which the sensors, actuators, and controllers are connected via a shared communication network. In comparison with traditional systems, the NCSs possess many advantages such as great flexibility, convenient maintenance, low cost of installation, and so on. Yet, along with these advantages, some challenging issues (bandwidth allocation, communication delay, packet dropouts, packet disorders, and channel fading) emerged and gave rise to much attention. Then most recently, the research on the NCSs has become a heated topic and many elegant results have been proposed. 1-29 For instance, in Reference 1, an optimal linear filter for the NCSs was designed with involving time-correlated fading channels.As for distributed NCSs, in Reference 2, both communication constraints (packet dropouts and quantization) and switching topology were addressed. Meanwhile, since communication delay inevitably exists and leads to poor performance, then References 3-7 deeply studied its negative effects when designing the controllers. In Reference 3,

“…However, in the aforementioned methods, the system simply passively accepts the communication constrains. Another effective method is networked predictive control (NPC), which can actively compensate for the delay and packet dropouts . The main idea of predictive control is to predict the future control inputs of the system, and then select the corresponding control input according to the current information of the delay and packet dropouts .…”

In recent years, with the development of different types of new energy sources, cross-area power systems (CAPS), whose purpose is to maintain reasonable distribution and power sharing among different areas, have gained great attention. In this paper, aimed at CAPS with random delay and packet dropouts in the process of data transmission, a novel wide-area stabiliser on sliding mode control (SMC) is designed. Such stabilisers mainly includes two parts: the design of the wide-area controller and compensation of the communication constraints. First, a new sliding mode switching function is proposed for designing the wide-area controller. Then, the networked predictive control (NPC) algorithm based on the designed controller is used to compensate the network-induced delay and packet dropouts in CAPS. Furthermore, the stability of the close-loop error system is proved. Finally, one three-area power system is employed to demonstrate the effectiveness of the proposed methods. The results verify that the stabiliser designed in this paper is reasonable and effective.

The strategy of observer‐based nonfragile control and fault‐detection over finite‐time horizon has been examined for a class of uncertain switched nonlinear networked control systems (NNCSs) contingent with time varying delays inferred by the networks from sensor to controller and controller to actuator. Also, in this study, an observer‐based fault detection control has been designed for the NNCSs. By making use of fault detection control as residual generator, the conveyed fault detection problem is then transformed into attenuation problem. By employing multiple Lyapunov function and average dwell time (ADT) approach, sufficient conditions in terms of linear matrix inequalities (LMIs) ensures the finite‐time boundedness (FTB) criterion of the resulting switched NNCSs with a prescribed disturbance attenuation. Subsequently, the preferred LMIs constraints realizes the controller and observer gains. Finally, two numerical examples are proffered to showcase the efficacity of the proposed technique.
