Spacecraft nonlinear attitude control with bounded control input
The research in this thesis deals with nonlinear control of spacecraft attitude stabilization and tracking manoeuvres and addresses the issue of control toque saturation on a priori basis. The cascaded structure of spacecraft attitude kinematics and dynamics makes the method of integrator …

Optimal control co-design of attitude control systems
Attitude control is the process of orienting a spacecraft toward a desired point in space. Conventional systems for attitude control have been designed without considering the compliant response of the spacecraft. This leads to complex control algorithms that avoid exciting vibrational modes of the …

Attitude control of a spacecraft using two SGCMGs
This thesis presents new methods for controlling spacecraft using Control-Moment Gyros (CMGs). CMGs generate torque to change and maintain a spacecraft's orientation. The CMG control system is used specifically to provide three-axis altitude stabilization, precision pointing control and …

Attitude control of an underwater vehicle subjected to waves
… these forces and moments. Application of sliding control techniques are then developed for the underwater vehicle longitudinal plane equations of motion. Computer simulations are used to demonstrate the dependence of underwater vehicle depth control upon the pitch control, and adaptive pitch …

Magnetic attitude control of LAICE satellite with aerodynamic stabilization
… fourth instrument is pointed towards nadir. The attitude determination and control system must achieve the attitude pointing requirements (5° from nominal attitude) with minimum of cost and low power. The satellite will therefore make use of magnetic torque coils augmented with aerodynamic …

Theoretical and Experimental Investigation of Attitude Control for Underactuated Spacecraft
This thesis investigates the detumbling and attitude control capabilities of an underactuated 3U-CubeSat used for ESSENCE mission developed by York University. Three different types of actuatorsexternal thrusters, magnetorquers, and reaction wheelsare considered in the nonlinear rigid-body control …

Nonlinear attitude control of spacecraft with strain-actuated solar arrays
… presents a mathematical framework for precision attitude control of a spacecraft using the inertial coupling between the spacecraft and solar arrays. The spacecraft with solar arrays is modeled as a one degree of freedom cylinder (rigid body rotation) with flexible appendages …

Attitude control via structural vibration : an application of compliant robotics
… review and present techniques for effecting and controlling the reorientation of structures "floating" in angular-momentum-conserving environments, applicable to both space robotics and small satellite attitude control. Conventional orientation control methods require either the usage of …
