    摘要:

    針對目前電子節(jié)氣門控制系統(tǒng)中存在的缺乏駕駛臨場感、非線性和未建模動態(tài)不確定性等缺點(diǎn),結(jié)合臨場感主從遙操縱理論,提出基于雙向伺服力反饋控制策略的電子節(jié)氣門控制系統(tǒng)。駕駛員目標(biāo)開度與節(jié)氣門實(shí)際開度位置偏差經(jīng)動態(tài)魯棒補(bǔ)償器控制電驅(qū)油門踏板角位移,使駕駛員感知反饋力;同時位置偏差通過基于等效控制的模糊滑??刂破骺刂齐娮庸?jié)氣門實(shí)際開度,使其準(zhǔn)確跟蹤目標(biāo)開度。通過仿真驗(yàn)證了所設(shè)計的控制策略的有效性。試驗(yàn)采用電控六自由度駕駛模擬器,結(jié)果表明,所設(shè)計的電子節(jié)氣門控制系統(tǒng)能夠精確修正開度位置偏差,增強(qiáng)駕駛臨場感,具有較強(qiáng)的魯棒性和自適應(yīng)性。

    Abstract:

    To eliminate the lack of driving tele-presence, the errors from nonlinearity and dynamic modeling uncertainty, the control algorism based on the bilateral servo with force feedback and the theory of master-slave tele-manipulation was presented for electronic throttle system. The position deviation between ideal angle and real angle was used as input signal. The dynamic robust compensator controlled the accelerator pedal by-wire to make driver’s perception of feedback force. The fuzzy sliding mode controller based on equivalent controlled the real angle of electronic throttle to track the ideal angle. The simulation presents effectiveness of the designed control algorism. The experimental results on the electronic 6-DOF driving simulator show that the control algorism can eliminate the position errors rapidly and accurately, provides driving tele-presence and enhances the robustness and adaptive ability.
