一种反馈线性化弹道跟踪制导律设计
A Traj ectory Tracking Guidance Law Based on Feedback Linearization Method
摘要
Abstract
A traj ectory tracking guidance law was designed for surface-to-air missile based on feedback linearization method.The feedback linearization method was used to get an accurate linear model from the mass model of missile.A guidance law was designed with the linear model and linear quadratic regulator(LQR)theory,and the work flow chart of the guidance system was proposed.A digital simulation with initial errors and random wind was carried out,and the feedback linearization(FL)guidance law was compared with LQR guidance law based on the small perturbance linear model.Results show that the FL guidance law obtained by the accurate linear model is better than LQR guidance law.关键词
