【Abstract】 In order to conduct experimental research of the explicit model predictive control algorithm,an ARM-Linux platform-based physical simulation control system of the explicit model predictive control algorithm is developed.This control system realizes the online computation process of the explicit model predictive control algorithm on the ARM-Linux platform,and transforms the online optimization programming problem of the traditional model predictive control system into online data search,simplifying the online computation procedure,speeding the online computation and reducing the online computation time.The procedures of off-line computation of the explicit model predictive control algorithm,the architecture of the physical simulation control system,the regions of the explicit controller and its corresponding optimal control law,the architecture of interface function and the architecture of the control system on the ARM-Linux platform are also presented.Finally,control results of the physical simulation control system of the explicit model predictive control algorithm are provided.更多还原
