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

An Architecture for Electronic Throttle Control Systems
SAE Technical Paper Series, 2003This paper presents an architecture for monitoring and controlling an electronic throttle control system. The architecture contains two processors, the MAIN and the MCP. The MAIN is responsible for calculating the desiredthrottle position and the MCP for positioning the throttle using feedback control.

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

Dynamic surface control of electronic throttle
2015 International Conference on Recent Developments in Control, Automation and Power Engineering (RDCAPE), 2015In recent times electronic throttles are more and more important in automotive engines so as to achieve better fuel economy, minimum vehicle emission and good drivability. One of the major component inside an automobile engine is throttle valve. The control of electronic throttle is actually the control of movement of plate through which amount of air ...

Switching control of a pneumatic throttle actuator
IEEE Control Systems, 1998A speed controller's primary input, for an internal combustion engine-based vehicle, is the throttle angle. The most common way to adjust the throttle angle setting is with a pneumatic actuator. When a faster and more accurate throttle response is desired, the pneumatic based system is generally replaced with a stepping motor mounted directly on the ...

Throttles and Dampers: Controlling the Engine of Membrane Fusion
Science, 1997Thomas H. SA¶llner Vesicles deliver cargo to targets in all parts of the cell. New findings in this issue show that two regulatory proteins, Ypt1p (a Rab-family member) and Sly1p (a Sec1-family member), bind to a SNARE protein located on the target.

On adaptive electronic throttle control for sport motorcycles
Control Engineering Practice, 2013This paper addresses the control of an electronic throttle body (ETB) for ride-by-wire applications in sport motorcycles. The systems dynamics are identified in closed loop, providing a description of the system in terms of linear dynamics augmented with friction effects.

Simulations of Robust Control of the Throttle Valve Position
2020 IEEE International Conference on Automation, Quality and Testing, Robotics (AQTR), 2020The paper presents design, modeling and simulation of robust control applied to the throttle valve position. For this purpose, the simplified mathematical model of the throttle valve is first presented. It consists of a second order system affected by parameters uncertainties. Because of these drawbacks, H2 and H-infinity methods are used to design the

An Adaptive Nonlinear Strategy of Electronic Throttle Control
SAE Technical Paper Series, 2004An adaptive electronic throttle control strategy is proposed with the aim to provide robust and precise positioning of the throttle plate. The control strategy consists of a PID controller and a nonlinear compensator of friction and limp-home effects. The adaptation mechanism includes auto-tuning and self-tuning algorithms.
