Lin, Chendi; Herber, Daniel R.; Vedant; Lee, Yong Hoon; Ghosh, Alexander; Ewoldt, Randy H.; Allison, James T. (AAS Rocky Mountain Section, 2018-02-05)Intelligent structures utilize distributed actuation, such as piezoelectric strain actuators, to control flexible structure vibration and motion. A new type of intelligent structure has been introduced recently for precision ...
Computationally-efficient modeling and optimization of strain-actuated solar arrays with tailored viscoelastic damping for spacecraft attitude control Lee, Yong Hoon; Vedant; Allison, James T. (2020-02-01)The recently-introduced strain-actuated solar array (SASA) spacecraft attitude control system (ACS) is expected to enable new levels of pointing precision for next-generation space observatories. Previous work has shown ...
Vedant; Allison,James T. (2019-10)The University of Illinois, in collaboration with NASA Jet Propulsion Laboratory (JPL) and NASA Ames Research Center, has developed a novel Attitude Control System (ACS) called the Strain Actuated Solar Arrays (SASA), ...
Vedant; Allison, James T. (2020-01-31)A new strategy for spacecraft attitude control, called Multifunctional Structures for Attitude Control (MSAC), is presented here. MSAC utilizes deployable panels as multifunctional structures to provide fine pointing and ...
