Title:
パドル電流測定値フィードバックのみを使用したジャイロなし遷移軌道太陽捕捉
Document Type and Number:
Japanese Patent JP5872145
Kind Code:
B2
Abstract:
Systems and methods for gyroless transfer orbit sun acquisition using only wing current measurement feedback are disclosed so that a spacecraft is able to maneuver itself to orient its solar panel to its maximum solar exposure spinning attitude. The disclosed systems and methods involve controlling a spacecraft maneuver using only the solar wing current feedback as the sole closed-loop feedback sensor for attitude control. A spin controller is used for controlling the spacecraft spin axis orientation and spin rate. The spin controller commands the spacecraft spin axis orientation to align with an inertial fixed-direction and to rotate at a specified spin rate by using a momentum vector. In addition, a method for estimating spacecraft body angular rate and spacecraft attitude is disclosed. This method uses a combination of solar array current and spacecraft momentum as the cost function with solar wing current feedback as the only closed-loop feedback sensor.
