Adaptive Identification Of Linear Time-delay Systems: From Theory Toward Application To Engine Transient Fuel Identification

摘要

The paper is of tutorial value. A theoretical treatment of adaptive (online) identification issues is reviewed side by side for linear time-delay systems (LTDSs) with state measurements and for single-input single-output (SISO) LTDS with output measurements. A class of parameter identification algorithms is then presented for SISO LTDS with known and unknown delays. An application of the proposed algorithms to transient fuel identification in a port-fuel-injected internal combustion engine is illustrated in an experimental study.
