This paper addresses the attitude path design of a remote sensing satellite in various imaging modes. The novel path design algorithm is based on local polynomial regression, which produces a smooth attitude path by receiving the size and timing of maneuvers in each axis according to the desired imaging mode. This algorithm is described for stereo and snapshot modes in an imaging operation. The adaptive robust tracking control (ARTC) law is designed using quaternion algebra to perform the required maneuvers in an attitude path. The ARTC structure includes a sliding mode strategy, a projection-based adaptive model compensation, and a linear feedback term. Suitable conditions for imaging in each mode and the time of taking the image are determined by defining and evaluating the attitude control indices. These indices are defined by the half-cone error along the payload line of sight and relative performance error as a jitter with a 3-sigma confidence level. Despite the challenges in the path design, such as smoothness, system agility, and finite time realization of indices, in a conventional stereo imaging mode, taking an image in the nadir-pointing attitude is neglected. As a result, our work provides suitable conditions for taking the image in this attitude with an interval of 1.2 s. Finally, numerical simulations and verification are performed using multidisciplinary simulation, indicating the effectiveness of the proposed algorithm and model-based ARTC law.

“…Owing to the mentioned characteristics, recently, these methodologies have been applied to solve spacecraft attitude control problem with uncertain inertia parameters, external disturbances or actuator faults. In [18], adaptive second-order SMC technique is investigated, and some finite-time controllers are proposed to solve attitude tracking problem. Quasi-continuous sliding mode controllers and differentiators are selected to design attitude tracking control schemes, while Lyapunov theory is used to globally force tracking errors to the neighborhood of the origin [19].…”

This paper investigates an attitude tracking maneuver problem for a rigid spacecraft with external disturbances, uncertain inertia parameters, actuator misalignments, and faults. First, all the uncertainty terms are split from the desired commanded control torque, and then, the nonsingular terminal sliding mode is implemented to design a fixed-time attitude tracking controller. Subsequently, an adaptive law is drawn into the attitude tracking controller to form a new control scheme, which eliminates the requirement of the upper bounds of all the uncertain terms. Besides, in the light of the concept of fixed-time stabilization, practical fixed-time convergence is achieved for attitude tracking errors. Finally, the numerical simulations are demonstrated to highlight the performance of the proposed controllers.

“…In [8][9][10], fast TSM and adaptive laws are employed to solve attitude stabilization or tracking problem. Based on geometric homogeneity and separation principles, global attitude controllers are proposed in [11][12]. Du and Li [13] adopt adding a power integrator and finite time theory to design attitude tracking controller and distributed attitude control law.…”
