Abstract: The diesel auxiliary power unit (APU) for series HEV is a
multiple-input multiple-output complex nonlinear system. For its
controller design, a simple identification method for robust control is
presented. As the modeling approach for gain scheduling control, the APU
is considered as a linear parameter varying system and the model
parameters are gridded into a finite set. In each operating point, the
system model is identified with the model uncertainty modeling
technique, which is expressed as a nominal model and an uncertainty
region. Finally, identification tests are performed with the proposed
method on the APU bench and experimental results show its validity.
