摘要
在发动机转速性能优化过程中,针对于传统滑模变结构控制在发动机转速控制中出现的转速抖振现象造成系统不稳定。传统的滑模变结构控制方法不能解决高频抖动问题,无法直接应用到系统中。为解决上述问题,提出通过采用模糊滑模变结构(F-SMC)的控制方法,消除高频抖振对控制器性能的影响.首先,在变结构控制变量的基础上引入模糊控制分量;其次对模糊控制分量进行了设计,并在MATLAB软件上进行了计算机仿真.仿真结果表明,采用模糊滑模方法使汽车发动机转速控制器可以提高系统的鲁棒性。
A fuzzy sliding mode variable structure (F-SMC) control method was put forward to eliminate the high frequency chattering in controller. Firstly, on the basis of the variable structure control variables, the fuzzy control components were introduced. Secondly, these components were designed and simulated with MATLAB software. Re-sults from the simulation show that, the fuzzy sliding mode method can improve system robustness of automotive en-gine speed controller.
