SELF-TUNING CONTROL OF A CONTINUOUS STIRRED-TANK REACTOR

In this paper a method of adaptive continuous-time controller design f or the control of a continuous stirred tank reactor is presented. The controlled output of the reactor is the reactant temperature, the cont rol input is the coolant flow rate. The control is based on the choice of an external model of the controlled system with recursively estima ted parameters. The pole location of the closed-loop transfer function is found through an LQ criterion minimisation. For controller design, the polynomial equation approach is adopted. Simulation results of re actor control, at prescribed operating conditions, are included.
