Abstract

In order to achieve precise and robust tracking control of electronic throttle (ET) systems subject to external disturbances and uncertainties, a novel 2-order discrete-time fast terminal sliding mode control (2-DFTSMC) approach is presented in the paper. Specifically, a novel recursive nonlinear discrete-time sliding surface is developed by utilizing the fast terminal sliding surfaces and principles of high-order sliding mode (HOSM). Compared with previous methods, the proposed hierarchical two-layer discrete-time sliding surface has the capability to suppress the chattering and reduce the tracking error. Then, in order to further improve the system convergence dynamics, the improved exponential reaching law and disturbance estimator are also employed. Rigorous theoretical analysis proves that the quasi-sliding mode (QSM) exists and the tracking error is reduced. Finally, through experimental comparisons, it is verified that the proposed 2-DFTSMC approach is superior to traditional DLSMC and DFTSMC, which demonstrates the advantages and effectiveness of the 2-DFTSMC scheme with the recursive discrete-time sliding surface.

基于指数到达法的电子节气门二阶离散时间快速终端滑动模式控制

为了实现受外界干扰和不确定性影响的电子节气门（ET）系统的精确鲁棒跟踪控制，提出了一种新的二阶离散快速终端滑模控制（2-DFTSMC）方法。具体来说，利用快速终端滑动曲面和高阶滑模原理，提出了一种新的递归非线性离散滑动曲面。与以前的方法相比，所提出的分层两层离散时间滑动面具有抑制抖振和减小跟踪误差的能力。然后，为了进一步改善系统的收敛动力学，还采用了改进的指数逼近律和扰动估计器。严格的理论分析证明了准滑模的存在，减小了跟踪误差。最后，通过实验对比，验证了所提出的2-DFTSMC方法优于传统的DLSMC和DFTSMC，证明了具有递推离散时间滑动面的2-DFTSMC方案的优越性和有效性。
