| Abstract: | A multi-objective optimal control model for nonlinear multilevel dynamical system is built in this paper. The existence of the solutions to this system and the controllability and the polykeys of the control are discussed. In order to obtain the global optimal solution, Uniform Design method is introduced to select initial feasible points, then an improved Hooke-Jeeves algorithm is proposed. The new algorithm and its corresponding software we developed has validated in more than 12 horizontal wells, which show their advantages such as less length of trajectory designed, more accuracy of target hitting and less time-consuming comparison with present conventional method. |
