The problems of Hinfin stability and stabilization for networked control systems (NCSs) with state and control signal quantizations are considered, and a new sector bound approach is proposed. Unlike the previous works, the transform of system models to uncertain systems is not needed, which results in that the proposed controller design method is simpler. Even for the NCSs with only state quantizations,...
This paper studies the problems of robust Hinfin performance analysis and controller design for continuous-time networked control systems (NCSs). A new type of Lyapunov functionals is exploited to derive sufficient conditions for guaranteeing the robust exponential stability and Hinfin performance of the considered system, and robust Hinfin controller design is presented. It is shown that the newly...
This paper studies the problems of stability analysis and state feedback controller design for continuous-time networked control systems (NCSs). Model of NCSs with multiple-packet transmission and packet dropout in both the sensor-to-controller channel and controller-to-actuator channel is derived, then the stability condition for NCSs with multiple-packet transmission is presented, and a new method...
This paper proposes a novel controller for STATCOM to enhance the inter-area synchronous stability. The main idea of this controller comes from the concept of area-COI (center of inertia). The potential of area-COI as a unified signal for synchronous in large scale interconnected power systems is explored. This new controller uses areas-COI information and keeps them synchronous. Dynamic model based...
In this paper, a nonlinear robust adaptive modulation controller (RAMC) for thyristor controlled series capacitor (TCSC) in interconnected power systems is developed. The controller drives centers of inertial of different areas (COIs) to maintain synchronous operation based on the dynamic COI signals obtained from the wide area measurement system (WAMS). The overall system model is established using...
