Embodiment Construction

[0010] Now, preferred embodiments of the present invention will be described in detail. In this specification and throughout the claims, unless the context clearly dictates otherwise, the following terms have the meanings obviously associated therewith: the meanings of "a" and "the" include plural references, and the meaning of "in" includes "in". and "Up".

[0011] Such as figure 1 As shown, in one illustrative embodiment, the present invention is implemented on a microcontroller 118 or digital signal processing (DSP) chip that is part of the throttle control system 100 . The throttle control system 100 includes a mechanical portion 102 and an electrical portion 110 . A typical type of mechanical portion 102 known in the art includes a throttle plate actuator 106, such as a direct current (DC) actuator motor, connected to the throttle plate ( throttle blade) 104. Typically, the throttle plate 104 is spint-loaded so as to tend to maintain a fixed position in the absence of...

Abstract

An electronic throttle controller (200) includes a feedforward control (222), a PID (224), a sliding mode control (226) and an adder (230). The PID (224) is capable of generating a first feedback term that compensates for an error signal. The sliding mode control (226) is capable of generating a second feedback term that incorporates a solution to a Lyapunov equation applied to the error signal with sliding gain being updated by an estimation of unknown dynamics. The adder (230) adds the first feedback term, the second feedback term and the feedforwardcontrol (222) so as to generate a control signal (232).

Description

technical field [0001] The present invention relates to control systems, and more particularly, the present invention relates to a tracking control design for an electronic throttle system. Background technique [0002] The electronic throttle control system controls the opening of a throttle valve by driving a direct current (DC) motor according to a desired throttle position requested by an advanced control. In this throttle control, a pulse width modulation duty cycle is generated based on a throttle position measurement and a demand position signal from a higher-level control or an accelerator position sensor that detects the accelerator position based on the amount of depression of the accelerator pedal. A PWM with a properly calculated duty cycle drives a DC motor through a gear set to open or close the throttle valve to the exact desired position, thereby controlling the amount of intake air to the engine. Feedback control of proportional, integral and derivative (PI...
