Abstract: The guidance and control of vertical takeoff vertical landing reusable launch vehicle face multiple constraints, large nonlinearity, and high dynamics during its return process. To overcome these difficulties, schemes of guidance and control adapted to variable characteristics and demands of every flight phase are designed based on the use and improvements of existing algorithms. Firstly, the features of the whole flight profile during the return process are analyzed and a dynamic model is developed. An initial plan is then brought up with the employment of typical guidance and control methods and its shortcomings are analyzed in detail. Improvements are made correspondingly including designing new iterative guidance with adaptive target-updating on the foundation of the estimated remaining working time and geometry relationship and establishing the adaptive guidance method for the final two flight phases with multi-constraints and an active disturbance rejection controller, leading to the formation of a new guidance and control scheme with strong anti-disturbance and adaptability. Finally, the results of mathematical simulation under small disturbances and large disturbances demonstrate the effectiveness of the two proposed schemes as well as strong anti-disturbance and robustness of the improved scheme.

Key words: vertical takeoff vertical landing, typical guidance and control, adaptive target-updating, adaptive guidance, active disturbance rejection control
