On-line measurement method of transmission backlash based on angular velocity and double-end angular position information

Numerical study on the jet dynamic through centrifuge spinning: influence of angular velocity

Velocity Measurement Using Angular- and Frequency- Correlation Techniques

Detecting and estimating the velocity of slowly moving targets from a moving platform is difficult due to the Doppler broadening of the ground clutter. The latest MTI (moving target indicator) technique employs STAP (spacetime adaptive processing) to reduce the clutter's signal and thus, is able to detect the target's speed [ 11. This technique has proven to be very effective for detecting high...

Lizarralde and Wen: Attitude Control without Angular Velocity Measurement

A New Open-Loop Fiber Optic Gyro Error Compensation Method Based on Angular Velocity Error Modeling

With the open-loop fiber optic gyro (OFOG) model, output voltage and angular velocity can effectively compensate OFOG errors. However, the model cannot reflect the characteristics of OFOG errors well when it comes to pretty large dynamic angular velocities. This paper puts forward a modeling scheme with OFOG output voltage u and temperature T as the input variables and angular velocity error Δω...

Hybrid attitude tracking of rigid bodies without angular velocity measurement

In this paper we address the problem of output-feedback attitude control of a rigid body in quaternion-coordinate space through a hybrid (switching) PD+ based tracking controller; we establish stability for all initial values in a compact subset which may be arbitrarily enlarged by increasing the control gains. Assumptions used in the literature such as supposing that the initial states lay in ...
