Abstract

The injection pressure control plays a critical role in modern diesel engines equipped with common rail injection systems. As a consequence, a considerable amount of research and development activities exists aimed at improving the control strategies. This paper first introduces a relatively high precision, real-time capable model of the common rail diesel injection system. Then, a novel adaptive control algorithm designed for the injection pressure regulation is proposed, based on the theories of the sliding mode control and the adaptive fuzzy logic. The stability of the control system is analyzed by using the method of Lyapunov function. Simulation experiment results indicate that the designed control law has preferable performance index, good instantaneous response characteristics and strong anti-disturbance ability.
