Abstract: A method for synthesizing an optimal control that ensures the existence and stability of sliding modes for a system of nonlinear ordinary differential equations is proposed. This method uses an auxiliary optimal control problem. The solution gives a control in analytical form. It is proved that the trivial solution of the closed-loop system is Lyapunov stable. Application of the proposed method to linear and quasi-linear systems of equations is demonstrated, and an illustrative example is discussed.

Key words: system design, optimal control, sufficient optimality conditions, sliding mode, stability.
