摘要
提出面向动态过程的混合动力电动汽车(HEV)多能源动力系统控制方法.针对城市公交HEV,建立HEV动力驱动模型,通过优化PID控制器参数实现提高HEV动态特性的目的.同时为了解决提高HEV动态特性而引起其动力能量消耗增大的问题,提出面向动态过程的HEV模糊PID控制方法,在线确定控制系统的PID离散控制参数的变化规律,控制HEV多能源动力总成工作.仿真结果表明,该方法既能保证HEV动态特性良好,又能有效控制HEV动力源输出,使HEV节能目标得以真正实现.
Control for the HEV propulsion system based on dynamic processes is proposed. Parameters of the controller are optimized in order to optimize the dynamic characteristics. For the purpose of solving the problem that the energy consumption will increase while the dynamic characteristics are optimized, fuzzy-PI-control is put forward for the HEV. The dynamic characteristic is than improved, and the output required from the engine and motor will not go beyond their ability, which allows the optimized target of the control strategy to be implemented.
