ALGORITHMS FOR THE SYNTHESIS OF A TEMPERATURE CONTROL SYSTEM FOR THE INNER TUBE HEAT EXCHANGER WITH A STEAM JACKET
Аннотация
The synthesis of a feedback propagation control law for an inner tube heat exchanger with a steam jacket is addressed in this text. A controller has been developed that, based on temperature measurements taken at four points. The maintains the output temperature at a specified level by acting on the steam jacket temperature. To determine the parameters of the plant, a linear quadratic optimal (LQ-optimal) algorithm is employed. In the considered case, the optimal controller includes a proportional–integral (PI) component, as well as an additional term that requires storing the control input over the current interval for its computation. The proposed linear quadratic optimal control strategy can also be applied to nonlinear systems, provided that the system is linearized in the vicinity of a given reference trajectory. The presented computational procedures for parametric identification make it possible to regulate the feedback propagation control law synthesis problem, thereby stabilizing the process of control law formation.
