A Study on the Application of GPC Implicit PID Algorithm in the Heat Exchanging Station Control System

This paper proposes a GPC (generalized predictive control) implicit PID control algorithm to the heat exchanging station control system, which has features of long time delay, time varying and non-linearity. In this study, the PID control plays a main role at the beginning of system operation, meanwhile the GPC algorithm carries on the online identification of structure parameters; When the system enters into the steady state after a period of time, the identified structure parameters are also close to the actual value, then GPC implicit algorithm implements the dominative control of the system. The simulation result of the MATLAB shows the effectiveness and feasibility of the proposed control scheme.
