This thesis applies pseudospectral optimal control theory to assess the achievable performance of a guided rocket in the terminal stage of flight. the performance is compared to a baseline obtained using conventional control (proportional navigation). Design methodology approach: a two stage trajectory optimization framework is constructed by combining a convex optimization based algorithm and the pseudospectral nonlinear programming (nlp) method. This research integrates the gauss pseudospectral method with a three degree of freedom simulation model to plan the landing trajectory. the model includes earth’s curvature, ground effects, and landing gear deployment. a linear active disturbance rejection controller manages vertical speed, while the l1 guidance method handles lateral control.
