Centrifugal pump is one of the most important energy conversion device widely used in almost all industrial fields. Improving operating performance of pump is of great significance for energy saving and safety in production. The asymmetrical distribution of flow field and radial force that will cause flow-induced vibrations which reduce operating stability and reliability of centrifugal pump were...
It is vital to calculate the relative position and pose in many important space missions, such as space formation, rendezvous and docking, space capturing and maintenance etc. It is a direction to get the relative position and pose based on computer vision currently all over the world. And this method is also valid for spacecrafts. In this paper, on the basis of the attitude dynamics of spacecrafts...
The integrated navigation Kalman filter of strapdown inertial navigation system/Global Positioning System/star sensor (SINS/GPS/SS) with pesudorange and quaternion as observation information, has been researched for space autonomous navigation. To improve the real-time working performance, the reduced-order Kalman filter based state decoupling is put forward. With the hypothesis that SS precision...
