There is a big difference between the turning control technology for four rocket pulse engines and other turning control technologies for vertical soft launched missiles. In view of this problem， the turning segment line motion equation， the attitude motion equation， and the turning information equation of the missile were established in this paper. The turning time sequence was designed， and a turning control strategy was designed by introducing the prediction model and the corresponding criterion. Based on the strategy， the parameter matching research was carried out. Finally， a large range of adjustment of the missile axis was realized by a simple device. A simulation example was given to verify the effectiveness of the proposed parameter matching relationship and the turning control strategy.
