Nonlinear attitude control of spacecraft with strain-actuated solar arrays
… 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 (infinite-dimensional system). The equations of motion that describe system evolution are derived using the …

Optimal control co-design of attitude control systems
… time. These new methods will be used to develop Strain Actuated Solar Arrays (SASA), an ACS that offers attitude stabilization capability at the nano-radian scale by actively canceling mechanical vibrations on the spacecraft. The precise levels of pointing are enabled by designing the system …

Advances in combined architecture, plant, and control design
… a complex co-design problem with the design of strain-actuated solar arrays for spacecraft precision pointing and jitter reduction. Nested co-design is utilized along with a linear-quadratic inner loop problem to obtain solutions efficiently. A simpler, scaled problem is analyzed to gain general …
