Abstract

The invention discloses an electronic throttle valve control system based on a dynamic sliding mode algorithm. The electronic throttle valve control system based on the dynamic sliding mode algorithmcomprises a PC, a control panel, a drive panel, an electronic throttle valve and a sensor, wherein the control panel is connected with the PC, the drive panel and the sensor, and the dynamic sliding mode control algorithm is programmed in the control panel, specifically, a control command of the PC and data of the sensor are received, corresponding operation is conducted, and then a control signalis output to the lower drive panel to drive a direct-current motor of the electronic throttle valve so that position closed-loop control over the electronic throttle valve can be achieved. The control system provided by the invention is small in jitter and error and high in safety and reliability.

Description

technical field [0001] This patent relates to an electronic throttle control system, more specifically, an electronic throttle control system based on a dynamic sliding mode algorithm. Background technique [0002] Different from the traditional throttle, the automotive electronic throttle can realize the precise control of the throttle opening through the electronic control unit (ECU), so that the engine is in the best working state. Many foreign automobile manufacturers have introduced various electronic throttles with good control characteristics and their corresponding electronic control systems, which form the electronic throttle control system (ETCS). The electronic throttle control system is used to precisely control the throttle opening, which can not only improve fuel economy and reduce emissions, but also provide rapid system response and obtain satisfactory handling performance; on the other hand, it can realize idle speed control, cruise control and The integrat...
