Asymmetric Modelling and Control of an Electronic Throttle
نویسندگان
چکیده
This paper presents an improved model for an automotive electronic throttle inspired on the behavior observed in real-time experiments. Due to a number of issues, particularly the return-spring, the performance of the throttle valve depends on whether it is opening or closing. This asymmetric behavior was taken into account to design a mathematical model of the throttle body and to derive a nonlinear asymmetric PI controller. The experimental demonstration suggests that considering an asymmetric term dramatically improves the performance of the controller. Copyright c © 2014 John Wiley & Sons, Ltd.

Robust Control of an Electronic Throttle System Via Switched Chattering Control: Benchmark Experiments
A robust controller with chattering is proposed based on a simplified model of an electronic throttle system. The chattering term provides robustness against un-modeled nonlinearities, e.g., limphome nonlinearity, parameter dispersion, and friction phenomena. As the simplified model of the throttle system can be seen to correspond to a horizontal one-degree-of-freedom robot manipulator, the pro...
متن کاملModelling and Control of Electromechanical Servo System with High Nonlinearity
Electromechanical servo plays important role in automation, robotics and automotive industry. Recent passenger cars are equipped with dozens of such actuators. Often, these actuators replace the original manual and/or mechanical solution by so called mechatronic design –mechanism, electric motor and computer control. Typical example of mechatronic design is the throttle for airflow control of a...
متن کاملNeural network-based sliding mode control of electronic throttle
In this paper a neural network based sliding mode controller for electronic throttle is proposed. Electronic throttle is considered as an uncertain linear system. The uncertainties, which consist of an unknown friction and spring torque are estimated by the neural network whose parameters are adapted in an on-line fashion. Control and adaptive laws guarantee the boundedness of all signals in th...

Introduction: Electronic portal imaging devices (EPIDs) are fundamentally used for instantaneous verification of the patient set‐up, block shape, and leaf positions during radiation therapy. In radiotherapy, situations arise in which an inclined PTV must be treated mutually with adjacent nodal regions. This methodology is most widely used for matching tangential/lateral breas...

T he study seeks to investigate both linear and nonlinear effects of oil price movement on critical macroeconomic variables (output, price and exchange rate) in Nigeria using ARDL modeling approach. Previous studies substantially relied on linear methods using VAR approach to unravel this links without a clear conclusion. In an attempt to seek better results in this study, we employ both l...
