车联网环境下电子节气门全局快速滑模控制

Global fast sliding mode controller for electronic throttle valve under the environment of IoV

车联网是目前汽车电子领域的研究热点,而车车通信是实现车联网的重要技术手段。为了提高车车通信过程中汽车电子节气门的控制性能,提出了基于Luenberger观测器的电子节气门全局快速滑模控制。具体来讲,首先,基于电子节气门的非线性模型,设计了Luenberger滑模观测器,以实现对节气门开度变化的在线估计;其次,以节气门开度误差为输入,通过李雅普诺夫稳定性理论设计了全局快速滑模控制器与外部扰动自适应律,以确保系统的稳定性和鲁棒性。最后,对提出的控制方法进行仿真验证,并与现有方法进行对比分析,仿真结果证明了所提出控制方法的有效性。

Internet of Vehicle （IoV） is the research hotspot in the field of automotive electronics, in which vehicle-to-vehicle （V2V） communication plays an important role. In order to improve the performance of electronic throttle control （ETC） in the process of V2V communication, a global fast sliding mode controller （SMC） with Luenberger observer for ET is proposed in this paper. Specifically, first, the Luenberger sJiding mode state observer is designed based on the nonJinear model of ET to online estimate the change of throttle opening angle; second, taking the opening angle error of ET as input signal, the global fast SMC and the external disturbance adaptive law is put forward according to the Lyapunov theory, which can guarantee the stability and robustness of ETC ; and finally, simulation ex- periments and comparisons are carried out, and the simulation results prove the effectiveness of the proposed approach.
