Introduction: Angular speed, also known as angular velocity, is a measure of how quickly an object rotates about an axis. It is often used in physics and engineering to describe the behavior of ...

The problem of estimating the angular speed of a solid body from attitude measurements is addressed. To solve this problem, we propose an observer whose dynamics are not constrained to evolve on any ...

In the identification of industrial robot joint system, in order to obtain the ideal frequency response of the system, additional excitation needs to be applied. The addition of excitation signals, ...
