Analysis for Predictive Control Algorithm in District Heating
Due to its characteristics of large time delay and large inertia, central heating pipe networks suits to be controlled by predictive control algorithm. In predictive control systems, adjustable parameters are immerged into the closed-loop polynomial and the explicit relationships are difficult to be found, which make the algorithm design difficult. In this paper, the closed-loop characteristics of multi-horizon predictive control strategy with feedback correction is analyzed, which shows that it is equivalent to a certain kind of pole-placement algorithm. This conclusion demonstrates the performance design of state-feedback predictive control easier to be achieved.
