This paper proposes generalized predictive implicit adapting algorithm based on the feature of time delay, time variation, uncertainty for heat engineering process and the requirement of real-time control. First, after analyzing heat supply process of consumer substation, it introduces fundamental generalized predictive control(GPC). IMC structure of fundamental GPC algorithm is given. Because fundamental GPC is a distinct algorithm, the on-line computational quantity is big and the real-time property is poor. Then, GPC implicit algorithm is analyzed. Control law of implicit adaptive algorithm and parameter identification equation are derived. Finally, GPC implicit adaptive algorithm is applied for heating process control of consumer substation of district heating. Simulation results prove the proposed scheme is effective and feasible.
