摘　　要：提出了一种基于分层优化策略和动态最优控制解法的非线性系统预测控制算法,该方法大大减小了在线计算量,使实时控制成为可能.给出了详尽的理论推导,以一个仿真算例证明了算法的正确、可行与有效性.A kind of nonlinear predictive control algorithm based on the hierarchical optimum strategy and dynamic optimum control method is treated as a limited horizon optimum control of a nonlinear discrete system, and the solution is obtained by the maximum principle. Meanwhile, by the hierarchical optimum strategy,the system is to be decomposed into two parts, the linear part and the nonlinear one. By estimation and coordination of the nonlinear part, the problem of nonlinear rolling optimization is reduced to a linear one. As a result, the amount of on-line calculation is reduced and it becomes possible to realize real-time control.
