| Abstract: | 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. |
