A Coordinated Approach for Throttle and Wastegate Control in Turbocharged Spark Ignition Engines

摘要：

This paper presents a control approach for turbocharged spark ignition engines that coordinates the throttle and wastegate air path actuators in order to improve driveability without signi.cant compromise in ef.ciency. The coordinated controller is based on a two-input single-output (TISO) architecture which can be tuned through classical frequency response techniques using linearizations of a nonlinear mean value engine model. A systematic tuning method for the TISO architecture based on prior work is recommended and explained. The controller is evaluated in simulation with a one-dimensional GT-Power model and its performance is compared to that of a controller that does not coordinate the throttle and wastegate.
