Adaptive Sliding Mode Control for Secondary O2 Feedback (Third Report) —Improvement of Adaptability by Using Prediction and Identification Sliding Mode Control—

Article of Honda R&D Technical Review Vol.13 No.2

Summary

Secondary O2 feedback is one effective method for reducing vehicle emissions, and the improvement of this performance yields even greater emissions reductions. This report details a significant advance in the algorithm for the sliding mode controls that were described in our first and second reports, and the application of this newly designed algorithm to secondary O2 feedback. The results show that feedback control performance was significantly improved under all engine loads and catalyst aging conditions. Moreover, the FTP mode emissions were reduced by 32 - 42%, and the emissions stability with respect to catalyst aging conditions was dramatically improved.
