Robust PI stabilization of a class of continuously stirred-tank reactors



This article deals with the stabilization of continuously stirred-tank reactors in the face of control input saturations and uncertain chemical kinetics. Using ideas from modeling-error compensation techniques, a first-order compensator is designed, and its ability to stabilize the reactor temperature at an arbitrary setpoint is shown. The dynamic part of the proposed controller is interpreted as a type of robust integral action to accommodate the modeling error.
