电子节气门鲁棒滑模控制仿真研究
|
Abstract:
针对电子节气门系统的非线性环节和外部干扰复杂多变的问题，结合电子节气门的结构特点，建立了电子节气门数学模型，提出了一种基于指数趋近律的非线性鲁棒滑模控制，并对其进行了控制仿真.实验结果表明，基于指数趋近律的滑模鲁棒控制不仅能满足快速到达期望节气门开度，实现高精度控制等要求，而且可以增强电子节气门系统对外界干扰的鲁棒性.
Aiming at the complex problems of the nonlinearities and external disturbances of the electronic throttle system, combining with the structure characteristics of the electronic throttle, this paper has established a mathematical model and proposed a robust nonlinear sliding mode control based on index reaching law. Simulation experiment results show that the proposed robust nonlinear sliding mode control based on index reaching law not only can meet the requirements of fast arriving at the expected throttle opening with high precision control, but also have stronger robustness to external disturbances on the electronic throttle system
