Adaptive control of automotive electronic throttle

Control Engineering Practice, 2006
An electronic throttle is a DC servo drive which provides precise, drive-by-wire positioning of the throttle plate. This paper presents an electronic throttle control strategy consisting of a PID controller, and nonlinear friction and limp-home compensators.

Self-tuning control of an electronic throttle

Proceedings of 2003 IEEE Conference on Control Applications, 2003. CCA 2003., 2004
A Self-tuning strategy for an electronic throttle servo-system is proposed in order to account for the variations of DC motor armature resistance, battery voltage, and limp-home position. Different self-tuning algorithms have been derived depending on the availability of armature current sensor and control strategy auto-tuning procedure.

Adaptive pulse control of electronic throttle

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
Precise control of electronic throttle is critical to driveability, fuel economy and emission performance of present day passenger vehicles. Due to cost, material and packaging constraints, the throttle open-loop dynamics may be fairly complex, exhibiting substantial nonlinearities among which friction plays a prominent role.

On practical control of electronic throttle body

2012 9th International Conference on Fuzzy Systems and Knowledge Discovery, 2012
An electronic throttle body is a nonlinear device that includes effects on dead time, transmission friction, throttle plate friction and return spring limp-home. The effects are problem to precisely control of electronic throttle regulation. In recent year, various control designs have been proposed. This paper presents a simple yet effective nonlinear

State estimation of an electronic throttle body

IEEE International Conference on Industrial Technology, 2003, 2004
Electronic throttle body is a device used in cars to regulate air inflow into the motor engine. Its good behavior is crucial for the superimposed engine speed control system. However, electronic throttle body is a highly nonlinear system. Moreover, the only measured variable is the throttle valve position, and it is measured by a cheap potentiometer of

Constrained optimal control of an electronic throttle

International Journal of Control, 2006
The overall vehicle performance is strongly influenced by the quality of the control of the electronic throttle -- a DC motor driven valve that regulates the inflow of air to the vehicle's engine. Designing a controller for the throttle system is a challenging task since one has to cope with two strong nonlinearities: the gearbox friction and the so ...

LPV Control of an Electronic Throttle

Volume 1: Aerial Vehicles; Aerospace Control; Alternative Energy; Automotive Control Systems; Battery Systems; Beams and Flexible Structures; Biologically-Inspired Control and its Applications; Bio-Medical and Bio-Mechanical Systems; Biomedical Robots and Rehab; Bipeds and Locomotion; Control Design Methods for Adv. Powertrain Systems and Components; Control of Adv. Combustion Engines, Building Energy Systems, Mechanical Systems; Control, Monitoring, and Energy Harvesting of Vibratory Systems, 2013
In this paper, a discrete-time electronic throttle model was developed based upon the parameters obtained through system identification. To design gain-scheduling controllers using LPV (linear parameter varying) scheme, the throttle was modeled as an LPV system, where the vehicle battery voltage and the non-linear friction coefficient are the ...

Electronic throttle identification and modeling

2013 International Conference on Process Control (PC), 2013
The methods of electronic throttle experimental identification together with optimization based parameters estimation are presented in this article . The parameters identified by this experimental identification were used as initial values of optimization variables in the problem of nonlinear optimization, where the cost function was non smooth.

Variable structure control of electronic throttle valve

IVEC2001. Proceedings of the IEEE International Vehicle Electronics Conference 2001. IVEC 2001 (Cat. No.01EX522), 2002
In recent years, the use of electronic throttle valve systems has been very popular in the automotive industry. However, there exist difficulties in controlling the electronic throttle valve because of multiple nonsmooth nonlinearities including stick-slip friction, backlash, and a discontinuous nonlinear spring involved in the system. To alleviate the

GPIO based backstepping control for electronic throttle

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
This paper mainly studies the angle tracking problem in electronic throttle system with unknown time-varying disturbances. Firstly, generalized proportional integral observer (GPIO) is used to estimate the time-varying disturbances including model uncertainties, friction torque and spring initial torque.
