Resonance Suppression of Servo System Based on State Equalizer Method

open access: yesSensors, 2022
Aiming at the problem of mechanical resonance faced by the servo control system of the aero-optical stabilization platform, based on the proportional integral and disturbance observer combination (PI+DOB) control algorithm, a state equalizer speed closed

Global Versus Local Lyapunov Approach Used in Disturbance Observer-Based Wind Turbine Control

open access: yesFrontiers in Control Engineering, 2023
This contribution presents a Lyapunov-based controller and observer design method to achieve an effective design process for more dedicated closed-loop dynamics, i.e., a maximal flexibility in an observer-based controller design with a large consistency ...

A Trustable Software with a Dynamic Loop Control Mechanism

open access: yes2010 5th International Conference on Future Information Technology, 2010
Unexpected infinite loop during software deployment period is an undesirable for every organisation since it can cause critical damages in various aspects. Most of the current protection methods will perform during the software development process using verification and validation processes.

Synthesis of lever-blade dampers with enhanced mechanical structure

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2015
Since the torsion bar represents just an elastic element, the energy dissipation in suspensions problem is highly relevant for its application. Currently in quality of a dissipation device in torsion suspension are used the hydraulic dampers with movable

Control system design of mechanical systems with time varying mechanical and control parameters

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2014
A new control framework of motion and/or vibration control system design for mechanical systems with a time varying mechanical and control parameters is studied. As examples of such time varying mechanical and control parameters, we can assume a variable
