| Abstract: | 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 ... |
