Abstract : "A class of electric fuel pump system equipped in More-electric Engines with variant loads is studied. A
novel robust control method based on a combined linear and quadratic integral sliding mode surface is proposed.
The linear sliding mode surface with improved exponential reaching law guarantees that nominal system has satisfying
performance with reduced chattering, while the quadratic integral sliding mode surface is responsible for
compensation of mismatched uncertainties, enhancing system’s robustness. Besides, mathematical model of electric
fuel pump with variant load and leakages is established, which reflects both steady and dynamic characteristics
of the fuel pump. In addition, it is proved that combined sliding mode surface can be reached in finite time and remains
there. Stability o"
