Finite receding horizon
WebModel predictive control is a form of control in which the current control action is obtained by solving, at each sampling instant, a finite horizon open-loop optimal control problem, using the current state of the plant as the initial state; the ... WebModel Predictive Control, also known as Receding Horizon Control (RHC), uses the mathematical model of the system in order to solve a finite, moving horizon, and closed loop optimal control problem [4]. Thus, the MPC scheme is able to utilize the information about the current state of the system in order to predict future states and control ...

WebApr 16, 2010 · Abstract. This paper revisits the stability issue of earlier model predictive control (MPC) algorithms where the performance index has a finite receding horizon and there is no terminal penalty in the performance index or other constraints added in online optimisation for the purpose of stability. Stability conditions are presented for MPC of ... WebA finite element dynamics model is first customized and further formulated into the optimal control problem; then, the single-neuron adaptive critic dual-heuristic programming (SNAC-DHP)-based controller is constructed in the finite receding horizon. ...
