Comparison of GPC Controller and a Pid Auto-Tuner for a Heating Plant

Generalised Predictive Control (GPC)1 is applied on the VVS-400 Heating/Ventilation System4. The temperature control performance of GPC is compared with the on-board PID auto-tuner under load disturbance condition. GPC seems to be not affected if the plant model is over-parameterized. Furthermore, any offsets are eliminated by the consequence of assuming CARIMA plant model.
