Estimation of Engine Combustion Parameters Under Induction Coil Disturbances

The paper outlines a possible approach to disturbance compensator design for the combustion diagnostics systems using sensors affected by the ringing disturbances originated from the electronic hardware containing the induction coils. The compensaton is based on the semi-physical approach. The advantage of the given compensation method compared with cutting techniques is demonstrated for a generic combustion LS estimation system in terms of comparative analysis of estimation results with and without compensator.
