|Abstract:||The state/parameter estimation problem is studied for a small-scale ICE CHP model. Three main groups of estimators with significant performance and com- plexity differences are analyzed: the Extended Kalman Filter (EKF) as an extension of the classical Kalman Filter; the generalized unscented Kalman filter (UKF) that uses the unscented transformation; and particle filtering like the particle filter with resampling (PFr) and the Ensemble Kalman Filter (EnKF)|
The internal combustion engine is modeled as a mean-value engine model connected with a static generator model and the heat recovery circuit is modeled with two lumped heat exchanger models; one for the coolant circuit and the other for the exhaust gases. The coolant circuit is connected with the engine through a lumped inner engine thermal model.
Experimental data sets are artificially generated to test the di¤erent estimators. Dynamic parameters of the mean-value engine model are identify when the CHP model is simulated in open loop. Additionally; relevant heat transfer coe¢ cients of the heat recovery circuit are monitored when the model is simulated in closed loop.
