The high pressure common rail fuel systems (HPCRFS) are widely utilized to meet EURO VI emissions and efficiency targets. The common rail pressure of the HPCRFS has to be extremely precisely and flexibly controlled because the common rail pressure determines the fuel injection pressure and the fuel injected quality. Therefore, an active disturbance rejection controller (ADRC) based control algorithm of the common rail pressure is proposed in order to catch up the rapid changes of the common rail pressure and balance the fluctuation of the common rail pressure. The simulation results show that ADRC based control algorithm of the common rail pressure has fast dynamic response and high control accuracy. Therefore, ADRC can be well applied to research and development on the control algorithm of the common rail pressure for the HPCRFS.
