This paper investigates the problem of robust guaranteed cost fault-tolerant control for networked control system with norm-bounded uncertain parameters. Both network-induced delay and data packet dropout are taken into consideration, and data packet dropout is regard as a kind of special delay. The synthetical delay is a interval time-varying delay, and possesses fast time-varying characteristic,...
This paper investigates the problem of robust H∞ fault-tolerant control for a class of uncertain nonlinear networked control system (NCSs) with external disturbance. A T-S fuzzy model is employed to represent the nonlinear controlled plant in the NCSs. Both networked-induced delay and packet dropout in transmission are addressed. By using Lyapunov-Krasovskii functional, introducing some slack matrices,...
The problem of robust fault-tolerant control for a class of nonlinear networked control systems (NCSs) with parameter uncertainties is investigated in this paper. A T-S fuzzy model is employed to represent the nonlinear controlled plant in the NCSs. Both networked-induced delay and packet dropout in transmission are addressed. By using Lyapunov-Krasovskii functional, the less conservative integrity...
Robust PID controller design for multivariable processes is studied in this paper based on loop-shaping Hinfin control. In order to implement the complex Hinfin controller, we propose a method to reduce it to a multivariable PID controller, and give a method to choose the pre-compensator which determines the performance of the closed-loop system. The main contribution of the design method is that...
In order to overcome the bad performance and deficiencies of main steam temperature control system, we combine model free adaptive control (MFAC) algorithm with conventional PID algorithm. This scheme incorporates the modeling and control together to form an integrated intelligent control mechanism. The MFAC-PID cascade control system is able to overcome time delays, non-linearity, disturbance and...
