Abstract

A method of modeling, simulating (transient), and designing controllers for turbocharged engine systems is presented. The method is specific to spark ignition (SI) engines equipped with pneumatic, spring diaphragm, wastegate actuators, with solenoid valve active boost control. The method revolves around the joint simulation of the engine with Ricardo WAVE software and the control algorithm with Simulink®. A component by component modeling approach is outlined using WAVE, including an experimental approach for modeling the solenoid valve. Controls are designed in MATLAB® using the Zeigler-Nicholss PID tuning method, and a new approach that uses system identification and state-space techniques. Simulink® is then used to produce a transient simulation of the turbocharged engine system.'
