A new sliding mode control (SMC) design approach using measure theory and Lyapunov functional candidate is presented for nonlinear control problems with disturbances. Lyapunov function is supposed for designing a sliding surface (SS). In fact, the problem that is considered is as follows. A state trajectory from a given initial point reaches a given point on a sliding surface in a short time, and then tends to the origin (equilibrium point) along the sliding surface. Measure theory approach with embedding process is used to solve such a problem in two phases. In the first phase, after designing an appropriate SS by a suggested Lyapunov function, an embedding is constructed to solve a time optimal control problem such that the system trajectory reaches the SS in minimum time, then in the second phase, using SS, a control is designed such that the system trajectory tends to the origin along the SS.
