摘要
建立了汽车传动系统模型,研究了实现发动机最佳燃油经济性的算法,考虑到系统模型的强非线性特征以及发动机节气门与变速器速比对汽车动态性能的耦合作用,给出了保证实现汽车的动力性能和最佳燃油经济性的综合控制算法。建立了具有双变量闭环回路控制的综合控制系统,设计出模糊控制器和PID控制器,最后通过仿真比较了两种控制方法对综合控制效果的影响。
The transmission system model of car is deduced. Considering the strong non-linear characteristics of system model and coupling effect on car dynamics between engine throttle opening and CVT ratio, the synthesized control algorithm which can keep car performance and fuel economy is given. The synthesized control system with the feedback of the engine throttle and CVT ratio is built. Fuzzy controller and PID controller are designed. The synthesized control effecting of the two control method are compared in simulation.
