| Abstract |
Electronic throttles are increasingly being used in automotive systems in order to improve vehicle
driveability, fuel economy, and emissions. The paper presents an analysis of the electronic throttle
body linear model. The analysis results in simplifications of the process model structure and controller
optimization procedure. A method of identification of the simplified process model is outlined. A
linear feedback/feedforward throttle position controller is algebraically optimized according to the
damping optimum. The linear controller is extended with a gain scheduling algorithm, in order to deal
with different process parameters for the regions below and above the limp-home position. The
proposed controller represents a core of the overall nonlinear electronic throttle control strategy which
also includes friction and limp-home compensators. The designed control system is examined by
computer simulation and experiment. |
