    摘要:

    为了提高汽车电子节气门开度控制的响应速度和精确度,研究与设计了一种非奇异快速终端滑模控制策略.建立了电子节气门控制系统的非线性数学模型;利用节气门阀片实际开度与期望开度的误差及误差的导数设计非奇异快速终端滑模面和终端吸引子,使用扩张状态观测器估计开度的一阶导数,设计了不存在奇异控制量且收敛快速的节气门非奇异快速终端滑模控制器,证明了这种控制器的李雅普若夫稳定性;对4种参考输入信号使用非奇异快速终端滑模控制和普通滑模控制在MATLAB/simulink 中进行了仿真.仿真结果表明,相比于普通滑模控制方法,非奇异快速终端滑模控制方法具有更短的调节时间和更小的跟踪误差,在4种参考输入信号的作用下,普通滑模控制器需要1 s甚至1.2 s的时间才可基本实现跟踪,且跟踪误差较大,而非奇异快速终端滑模控制器可确保电子节气门开度在0.1 s实现对参考信号的跟踪,且跟踪误差的绝对值小于0.2°,同时冲击扰动信号作用下的仿真结果表明非奇异快速终端滑模控制器具有较好的鲁棒性.

    Abstract:

    In order to improve the response speed and accuracy of automotive electronic throttle valve opening control,a Non-singular Fast Terminal Sliding Mode (NFTSM) control strategy was designed.Firstly,the non-linear mathematical model was obtained by analyzing the nonlinear and disturbance of the electronic throttle valve control system.Secondly,a NFTSM surface and a terminal attractor were constructed by using the error between electronic throttle opening and the desired opening and the derivative of the error,at the same time,an extended state observer was applied to estimate the first order derivative of the opening degree.Meanwhile,a NFTSM controller with no singular control and fast convergence was designed,which verified the stability of the controller by using Lyapunov's stableness theory.A number of simulations were conducted to test and verify the performances of the NFTSM control method and conventional sliding mode control method in MATLAB/simulink by using sine signal,step signal,triangle wave signal and approximate stair-step signal as the input signals respectively.The simulation results show that the NFTSM control method has shorter settling time and smaller tracking error compared with the conventional sliding mode control method.NFTSM controller can keep the electronic throttle opening consistent with reference signals in 0.1 s and has steady-state error less than 0.2°,while the conventional sliding mode controller needs more than 1 s and has large tracking error.In addition,the simulation results of the system under the impulsive disturbance signal show that the NFTSM controller has excellent robustness.
