| Abstract: | The PID controller of hydrogen engine on idle working conditions was designed,which can make the speed quickly approach target speed and make the engine idle stably.The control strategy of excess air ratio on idle working conditions is put forward,excess air ratio is controlled in open-loop using Kalman prediction algorithm under transient conditions,meeting the realtime requirements;excess air ratio is controlled in closed-loop using Kalman filtering algorithm under steady conditions,meeting the high accur... |
