Abstract: This paper mainly focuses on stability analysis of the nonlinear active disturbance rejection control (ADRC)-based control system and its applicability to real world engineering problems.

For over a century, scientists have thought of time as a fundamental property of the universe. But the more researchers seek ...

In a grandfather clock, a pendulum swings back and forth and this periodic motion is maintained using the energy stored in its suspended weights. This is done with the help of the escapement mechanism ...

Abstract: The double inverted pendulum (DIP) system is a benchmark underactuated mechanical system. The control problem of the DIP system is challenging since it not only has high nonlinearity, but ...

During spin training in a Pitts S-2B, the aircraft entered an inverted condition before rapidly developing into a full spin. With lift disrupted and airflow unstable, the aircraft began rotating ...

Witness the incredible maneuverability of the Fairchild Republic A-10 Thunderbolt II as it performs an inverted pass and high-alpha flight with extreme precision and control. Known for its rugged ...
