Target Yaw 0°

Initial truss orientation at Target Yaw 0 degrees

Control Result

The initial orientation of 0° was maintained stably until the end of the simulation.

Truss control result at Target Yaw 0 degrees

Thruster Output

Only small corrections were required to maintain the orientation, with almost no thruster output.

Target Yaw +45° / +90°

Target Yaw +45°

Control Result

The payload converged smoothly to the target yaw angle of 45° and maintained a stable orientation afterward.

Truss control result at Target Yaw plus 45 degrees

Thruster Output

Thrust was applied during the initial rotation, followed by almost zero output after reaching the target angle.

Target Yaw +90°

Control Result

The payload converged stably to the target yaw angle of 90° and maintained the orientation after reaching it.

Thruster Output

Thrust was applied for a longer period than in the +45° case, but the output dropped to nearly zero after reaching the target angle.

Target Yaw -45° / -90°

Target Yaw -45°

Control Result

The payload converged smoothly to the target yaw angle of -45° and maintained a stable orientation afterward.

Truss control result at Target Yaw minus 45 degrees

Thruster Output

The output characteristics were symmetric to the +45° case, with the thrusters for the opposite rotation direction used selectively.

Target Yaw -90°

Control Result

The payload converged stably to the target yaw angle of -90° and maintained the orientation after reaching it.

Thruster Output

The output characteristics were symmetric to the +90° case, with almost zero output after the initial rotation.

Comparison with Part 1

The Target Yaw +90° control result is compared with the Part 1 result.

Part 1: Target Yaw +90°

Part 1 truss control at Target Yaw plus 90 degrees

Part 2: Target Yaw +90°

Part 2 truss control at Target Yaw plus 90 degrees

In Part 1, high output from multiple thrusters continued even after the payload reached the target angle. In Part 2, the payload approaches the target angle more gradually, while the thruster output decreases progressively, reaching an almost zero-output state after the target angle is reached.
