Design and Simulation of a Flexible Bending Actuator for Solar Sail Attitude Control

Design and Simulation of Sailcraft Attitude Control Systems Using the Solar Sail Control Toolbox

A MATLAB-based software tool, called the Solar Sail Control Toolbox, has been developed for solar sail analysis, design and simulation. The toolbox includes functions for multibody dynamic modeling, attitude control systems design, thrust vector control design, orbit analysis, solar sail mission analysis, thermal analysis and power subsystem analysis. Sailcraft models can be created, analyzed a...

Flexible Models for Solar Sail Control

Solar sails employ a unique form of propulsion, gaining momentum from incident and reflected photons. However, the momentum transferred by an individual photon is extremely small. Consequently, a solar sail must have an extremely large surface area and also be extremely light. The flexibility of the sail then must be considered when designing or evaluating control laws. In this paper, solar sai...

simulation and design of electronic processing circuit for restaurants e-procurement system

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...

Attitude Stability and Altitude Control of a Variable- Geometry Earth-Orbiting Solar Sail

Design of Nonlinear Robust Controller and Observer for Control of a Flexible Spacecraft

Two robust nonlinear controllers along with a nonlinear observer have been developed in this study to control a 1D nonlinear flexible spacecraft. The first controller is based on dynamic inversion, while the second one is composed of dynamic inversion and µ-synthesis controllers. The extension of dynamic inversion approach to flexible spacecraft is impeded by the non-minimum phase characteristi...
