Development of Electronic Throttle Control Utilizing Adaptive Control Method

Article of Honda R&D Technical Review Vol.14 No.2

Summary

Electronic throttle control has been focused upon in recent years as a measure to provide greater accuracy for idling air control and to help reduce emissions. For this reason, it is necessary to achieve greater robustness in throttle control performance, to cope with variations between individual units and degradation of parts over time. Up to the present, it has been difficult for PID control systems to recognize unspecified disturbances, and this has been an impediment to achieving a balance between robustness and responsiveness. To perform robustness, an adaptive control system has been constructed which utilizes sliding mode control and contains an identifier to perform sequential calculations. This technology has realized previously unavailable levels of robustness, accuracy, and responsiveness in an electronic throttle control.
