Comparison of Optimal and Bioinspired Adaptive Control Laws for Spacecraft Sloshing Dynamics

Non-Linear Control Strategies for Attitude Maneuvers in a CubeSat with Three Reaction Wheels

“…It is defined by [12] as a measure of magnitude equivalent to the effective average torque exerted on the three satellite axes. This parameter is similar to the thruster activity performance metric defined in [21].…”

“…Precision, computational cost, and stability are used as evaluation criteria in [20]. In [21], a performance index that considers both the thruster activity and the attitude tracking performance is used.…”

“…The adapted formula to calculate it with Quartenions is described in (62). This parameter is similar to the attitude tracking performance metric defined in [21]. • Average of Square of the Commanded Control Torque (ASCCT).…”

Attitude-pendulum-sloshing coupled dynamics of quadrotors slung liquid containers

“…Feedback control schemes measure motions of the liquid surface in a feedback loop for oscillations suppression. [17][18][19][20][21][22][23][24][25] Nevertheless, accurately sensing the sloshing states is challenging. Open-loop control techniques modify the driving commands to generate a prescribed motion with minimal sloshing.…”

“…All abovementioned works are only focused on sloshing dynamics. Additionally, some of works [17][18][19][20][21][22][23][24][25][26][27][28][29] described sloshing dynamics using the equivalent mechanical model, such as the pendulum model. However, the equivalent pendulum model for fluid-sloshing dynamics is significantly different from attitude-pendulum-sloshing dynamics.…”
