LPV Control for the Air Path System of Diesel Engines

This paper addresses the gain scheduled H
_infin
control issue for the air path system of diesel engines. The air path system is modeled as a linear parameter varying (LPV) system, where the system matrices are dependent on two exogenous variables: the engine speed and the turbine vane position. The open loop frequency property is presented as well as the detailed synthesis procedure of the gain scheduled controller such as the weighting function selection and design. A comparative study between the gain scheduled LPV control and the H
_infin
control is investigated. Simulation results are shown to demonstrate the effectiveness of the gain scheduled LPV controller.
