This brief is devoted to the power-constrained low-thrust optimal control problem (OCP). First, a general model for a class of power constraints is proposed by defining a piecewise …
The idea of using air thrusts for vibration control of structures has gained attention since the 1990s. However, only discontinuous controllers and switching functions have been studied …

The high-precision alignment of spacecrafts subject to multiple composite disturbances [eg, axle frictions and back electromotive force (EMF)] and mandatory pointing constraints is an …
Low-thrust propulsion systems are widely used in space missions due to their high specific impulse and reduced propellant consumption. However, current research focuses on …
