Higher order integral nested sliding mode control of internal combustion engine

In this paper, a controller for internal combustion engine is presented. This scheme is based on the combination of high order sliding mode, integral sliding mode and globally linearizing strategies. That technique is used to find a control law such that output is related linearly to the input, i.e. to find a suitable equation eliminating the non-linearity between output and input. The integral sliding mode control is used to guarantee the robustness of the closed-loop system, and the high order sliding mode control is applied to track the reference signal, to reject perturbations and to estimate a certain unknown value of the system by means of the equivalent control method.
