In this lecture the receding horizon control (RHC) principle is described and the main ingredients required for its stability are discussed. After a brief review of Lyapunov stability, the use of terminal cost, constraint and controller is shown in a discrete-time constrained nonlinear system formulation. Treatment of stability is also illustrated in a continuous-time unconstrained nonlinear system setting, using a control Lyapunov function (CLF)-based terminal cost.
