摘要 针对可重复使用运载器(RLV)再入模型的非线性模型控制问题,设计了基于控制角与控制力矩间全反馈(非时标分离)条件下的反馈线性化控制器,实现RLV六自由度非线性模型线性化,应用经典的PID控制理论实现了控制律设计,完成了全弹道仿真.仿真结果验证了控制方法的可行性,实现了制导指令的精确跟踪. The re-entry model of reusable launch vehicle（RLV） is highly nonlinear and coupled,so the classical control is very difficult to meet the control requirements.Aiming at this problem,feedback linearization controller was designed based on the full rotational equations of motion rather than on a conventional model derived from time-scale separation,and RLV nonlinear model of six degrees of freedom was linearized by this method,and then control system was designed by using the classical PID control theory,and finally the entire trajectory simulation was completed.The simulation results show that the control method can accurately track guidance command.
