| ABSTRACT |
|
With the rapid development of diesel engines, reducing the pressure fluctuation of the common rail has
become a key factor to improve the performance of the high pressure common rail (HPCR) system. Among traditional rail
pressure control approaches, the influence of time-varying disturbances on the HPCR system is not fully considered and is
not well dealt with. To this end, a nonlinear model of the HPCR system is firstly established based on fluid dynamics and
mechanics laws. And a composite controller based on the nonlinear model is proposed. It consists of two parts: 1) A sliding
mode feedback part; 2) A disturbance feedforward compensation part based on a generalized proportional integral observer.
Finally, a group of test is simulated in the AMESim simulation environment and the results are shown to demonstrate the
effectiveness of the proposed method. |
