The Guidance Method on Midcourse Orbit Transfer Based on Improved Velocity Augmentation

变轨技术的核心是控制单元的算法部分。基于对传统速度增益制导律的认识,提出了一种基于改进的速度增益制导方法,解决中段改变打击目标的实时控制问题。通过建模、仿真,验证了算法的可行性。

The application of orbit transfer technology can advance the capability of penetration for aircraft in the battlefield. The arithmetic which is used in control system is the core of orbit transfer technology. On the basis of understanding traditional velocity augmentation guidance method, a guidance method based on improved velocity augmentation is proposed. This method can solve the real-time control problem of chan- ging the strike target in midcourse. The validity and efficiency of the method are proved by modeling and simulation.
