Latest Patents

Yukai Zhu's latest patents include two notable inventions. The first patent is titled "Method for disturbance compensation based on sliding mode disturbance observer for spacecraft with large flexible appendage." This invention provides a method for disturbance compensation that involves building a spacecraft attitude control system and constructing an external system that incorporates uncertain portions of the damping and rigidity matrices of the spacecraft's flexible appendage. The method also includes configuring a sliding mode disturbance observer to estimate the sum of flexible vibration and environmental disturbance, ultimately leading to a compound controller that compensates for these disturbances.

The second patent is "Method for attitude controlling based on finite time friction estimation for flexible spacecraft." This invention outlines a control method that introduces flywheel friction disturbance into a flexible spacecraft dynamics system. It involves converting the dynamics system into a state-space form, constructing a flywheel friction disturbance estimator, and combining it with a flexible appendage vibration disturbance observer to create a compound controller. This controller compensates for both flywheel friction and flexible appendage vibration disturbances.
