| Abstract: | Constructed in this paper is the dynamic mathematic model for a fuel cell car powertrain which is composed of fuel cell engine,DC motor and its controller,and power battery pack.Based on the noise characteristic of the powertrain,the linear quadratic optimal control of powertrain is boiled down to a linear quadratic Gauss problem,and a linear quadratic optimal control algorithm for the powertrain is established taking into account the influence of random disturbance.The off-line simulation and chassis dynamometer test show that the algorithm can take into full account the performance and fuel economy of fuel cell car powertrain,attaining set control objective. |
| Keywords: | Fuel cell car Powertrain Modeling Linear quadratic optimal control |
