针对传统广义预测控制算法的计算量大这一缺陷 ,通过对未来的控制序列的离线近似计算 ,而只精确求解当前时刻要实施的控制量 ,提出了一种广义预测控制的快速算法。该算法简单 ,不必求解Diophantine方程和逆矩阵 ,大大减小了在线计算量。仿真结果表明 ,该算法具有良好的控制性能 。

To avoid large amounts of computations of the traditional generalized predictive control algorithms (GPC), a fast algorithm of GPC is presented by off-line appr oximate computation of the future control sequences. The algorithm is simple and it is not necessary to solve the Diophantine equation and the inverse matri x so that the on-line amounts of computation are reduced greatly. The simulatio n results show that the algorithm has perfect control quality and has strong con straint on the control action.
