Stability analyses of hybrid dynamical systems for the control system with a pulse-width-modulated sampler
Proceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527) - Tập 1 - Trang 350-354 vol.1
Gao Rui
In the present paper, using the analysis method of hybrid dynamical systems (HDS), we do some research works for a class of pulse-width-modulated sampling control system based on the existing results of asymptotic stability of HDS invariant sets. In the case that there is a certain periodic perturbation imposed on the system's object, the exponential stability qualifications are proved strictly in...... hiện toàn bộ

Controller optimisation of a tube heat exchanger
Proceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527) - Tập 1 - Trang 54-58 vol.1
D. Dugdale, Peng Wen
This study seeks to improve the process control of an ammonia/steam heat exchanger by optimising the existing PID controllers. The exit ammonia temperature of the heat exchanger is maintained by the combination of three PID controllers, an ammonia temperature controller, a pressure controller and a steam pressure controller. Originally, the pressure and temperature controllers were de-tuned to pre...... hiện toàn bộ

Mixed l/sub 1//H/sub 2/ control for MIMO systems
Proceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527) - Tập 1 - Trang 268-272 vol.1
Shengping Li
In this paper we consider the mixed l/sub 1//H/sub 2/ control problem for multiple input-multiple output (MIMO) discrete-time systems. This problem is formulated as minimizing the l/sub 1/-norm of a closed-loop transfer matrix while maintaining the H/sub 2/-norm of another closed-loop transfer matrix at prescribed level. The continuity property of the optimal value respect to changes in the H/sub ...... hiện toàn bộ
