Quasi-LPV gain scheduling control for the air path system of diesel engines

This paper addresses the issue on gain scheduled quasi linear parameter varying (LPV) control strategy for the air path system of diesel engines, which plays a critical role for the emission reduction of diesel engines. Due to the strong nonlinearities of the underlying system, traditional linear control algorithm can not achieve a satisfactory control performance. In this paper, the considered nonlinear plant is approximated as an Hammerstein quasi-LPV system in the first place. An advanced quasi-LPV gain scheduled control strategy is applied to the underlying system. The effectiveness of the new control algorithm is illustrated by the simulations.
