Latest Patents

One of Wie's latest patents is titled "Singularity escape/avoidance steering logic for control moment gyro systems." This innovative steering logic utilizes a mixed weighted two-norm and least squares optimization solution to overcome the challenges associated with momentum saturation singularities. By incorporating an additional weighting matrix, W, along with deterministic dither signals in a weighting matrix V, this new approach effectively avoids troublesome internal elliptic singularities that are commonly encountered in other pseudoinverse-based steering logic. The patent describes various control moment gyro (CMG) systems, including a typical pyramid array of four single-gimbal CMGs and configurations used in the International Space Station, demonstrating the simplicity and effectiveness of the new steering logic.

Another significant patent by Wie is "Continuous attitude control that avoids CMG array singularities." This invention addresses the pseudo inverse singularity problem that arises when there are more actuators than dimensions in the controlled space. The system employs both closed and open loop control of the CMGs to reorient the satellite while detecting potential singularities and issuing signals to avoid them. This technology can also be applied to robotic arm manipulators, showcasing its versatility.
