چکیده

* Graduate Research Assistant. Student Member AIAA. † Professor. Fellow AIAA. ‡ Lockheed Martin Assistant Professor of Avionics Integration. Member AIAA. Future reusable launch vehicles must be designed to fly a wide spectrum of missions and survive numerous types of failures. The X-33 Reusable Launch Vehicle Technology Demonstrator is used as a simulation platform for testing a neural network-based model-reference adaptive controller and comparing it to a gain scheduled controller in the case of a mission undergoing an engine-out abort scenario. The adaptive controller is able to perform nearly as well as a gain-scheduled controller, and suggestions are made for further improvements.

Nonlinear Optimal Control Techniques Applied to a Launch Vehicle Autopilot

This paper presents an application of the nonlinear optimal control techniques to the design of launch vehicle autopilots. The optimal control is given by the solution to the Hamilton-Jacobi-Bellman (HJB) equation, which in this case cannot be solved explicity. A method based upon Successive Galerkin Approximation (SGA), is used to obtain an approximate optimal solution. Simulation results invo...

Robust Integral Sliding-Mode Control of an Aerospace Launch Vehicle

An analysis of on-line autonomous robust tracking controller based on variable structure control is presented for an aerospace launch vehicle. Decentralized sliding-mode controller is designed to achieve the decoupled asymptotic tracking of guidance commands upon plant uncertainties and external disturbances. Development and application of the controller for an aerospace launch vehicle during a...

Evaluation of an Adaptive Method for Launch Vehicle Flight Control

the amount of analysis and testing required per mission must be reduced over that performed for the partially re-usable Space Shuttle. A goal for future RLV flight control is to design and test the flight control system to operate within a prescribed flight envelope and loading margin, and requiring only payload/fuel parameters and “route” to be specified for a given mission. It has been estima...

Adaptive Quaternion Attitude Control of Aerodynamic Flight Control Vehicles

Conventional quaternion based methods have been extensively employed for spacecraft attitude control where the aerodynamic forces can be neglected. In the presence of aerodynamic forces, the flight attitude control is more complicated due to aerodynamic moments and inertia uncertainties. In this paper, a robust nero-adaptive quat...

Adaptive attitude controller of a reentry vehicles based on Back-stepping Dynamic inversion method

This paper presents an attitude control algorithm for a Reusable Launch Vehicle (RLV) with a low lift/drag ratio (L/D < 0.5), in the presence of external disturbances, model uncertainties, control output constraints and the thruster model. The main novelty of proposed control strategy is a new combination of the attitude control methods included backstepping, dynamic inversion and adaptive cont...
