THROTTLE CONTROL OF THE HYDRAULIC DRIVE BY MEANS OF A SEQUENTIAL THROTTLE
COLLECTION OF SCIENTIFIC PAPERS, 2023The article is devoted to the problem of solving the problem of regulating the speed of the output link of the hydraulic drive by means of a sequential throttle with the discharge of the working fluid into the storage tank, bypassing the hydraulic motor.

Adaptive control of automotive electronic throttle
Control Engineering Practice, 2006An 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.

On the Toyota's Throttle Control Problem
2010 IEEE/ACM Int'l Conference on Green Computing and Communications & Int'l Conference on Cyber, Physical and Social Computing, 2010This work tackles two research threads. The first thread evaluates the use of conventional design versus electronic engine control by applying real-time control theory. The second thread, which will be explored in a longer version of this paper, presents a formal method that determines if the system matches the specifications.

Self-tuning control of an electronic throttle
Proceedings of 2003 IEEE Conference on Control Applications, 2003. CCA 2003., 2004A 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.

We have all heard stories about runaway vehicles that accelerate uncontrollably and collide with other vehicles, crash into buildings or run people over. The circumstances often sound familiar and are sometimes tragic. The vehicle accelerates for no apparent reason and the driver is said to have been rendered helpless in an out-of-control machine.

Adaptive pulse control of electronic throttle
Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001Precise 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, 2012An 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

Constrained optimal control of an electronic throttle
International Journal of Control, 2006The 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, 2013In 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 ...

Variable structure control of electronic throttle valve
IVEC2001. Proceedings of the IEEE International Vehicle Electronics Conference 2001. IVEC 2001 (Cat. No.01EX522), 2002In 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
