Global stabilization of exothermic chemical reactors under input constraints
نویسندگان
چکیده
Ah&act-This paper is devoted to the temperature control and the stabilization under input constraints of exothermic chemical reactors. We first consider a reactor in which a single and exothermic reaction takes place and design state feedback controllers to achieve the global and robust stabilization under input constraints of the reactor. Then, we extend these results to a general class of exothermic reactors in which multiple coupled chemical reactions can take place.

Adaptive sampled-data tracking for input-constrained exothermic chemical reaction models
We consider digital input-constrained adaptive output feedback control of a class of nonlinear systems which arise as models for controlled exothermic chemical reactors. Our objective is set-point control of the temperature of the reaction, with prespecified asymptotic tracking accuracy set by the designer. Our approach is based on λ–tracking controllers, but we introduce a piecewise constant s...
متن کاملRobust Feedback Stabilization of Chemical Reactors - Automatic Control, IEEE Transactions on
This paper deals with the temperature stabilization of a large class of continuously stirred tank chemical reactors. We design state feedback controllers, and we show their ability to globally stabilize the temperature at an arbitrary set point in spite of uncertainties on the kinetics. Furthermore, it is also shown that these controllers can handle input constraints along the closed-loop traje...

متن کاملRobust Adaptive Attitude Stabilization of a Fighter Aircraft in the Presence of Input Constraints
The problem of attitude stabilization of a fighter aircraft is investigated in this paper. The practical aspects of a real physical system like existence of external disturbance with unknown upper bound and actuator saturation are considered in the process of controller design of this aircraft. In order to design a robust autopilot in the presence of the actuator saturation, the Composite Nonli...
متن کاملRobust Static Output Feedback Stabilization of an Exothermic Chemical Reactor with Input Constraints
Robust static feedback stabilization of linear systems with uncertainties and bounded control inputs is studied. Necessary and sufficient conditions of positive invariance of polyhedral domains with respect to motion of uncertain linear systems are formulated together with conditions ensuring the asymptotic stability of uncertain linear systems with bounded control inputs. The problem of robust...
