摘要
针对约束模型预测控制在线求解的计算复杂性 ,在标准预测控制滚动求解思想的基础上提出了一种有效可行的快速算法 ,即在每一时刻 ,只精确求解当前要实施的控制量 ,对未来的控制序列则用线性反馈控制器来近似 ,从而降低了预测控制在线求解的维数 ,提高了算法实施的快速性 .简化造纸机控制系统的仿真结果说明了该算法的有效性 .
An efficient fast algorithm for constrained model predictive control (MPC) system was presented. It approximates the future control sequences off line by a set of stabilizing linear feedback control profiles, and only computes the current control action at k time instant exactly, thus can greatly reduce the on line computational burden of MPC and is especially suitable for large scale constrained systems. The simulation result of a simplified paper machine cross directional (CD) control problem demonstrates its effectiveness.
