Supporting brace sizing in structures with added linear viscous fluid dampers: A filter design solution [PDF]
, 2014 Viscous fluid dampers have proved to be effective in suppressing unwanted vibrations in a range of engineering structures. When dampers are fitted in a structure, a brace is typically used to attach them to the main structure. The stiffness of this brace

Hierarchical Control of Nonlinear Active Four-Wheel-Steering Vehicles
Energies, 2018 A new type of hierarchical control is proposed for a four-wheel-steering (4WS) vehicle, in which both the sideslip angle and yaw rate feedback are used, and the saturation of the control variables (i.e., the front and rear steering angles) is considered.

Acceleration Analysis of 3DOF Parallel Manipulators
Global Journal of Researches in Engineering, 2013 This paper presents a new approach to the velocity and acceleration analyses 3DOF parallel manipulators. Building on the definition of the ‘acceleration motor’, the forward and inverse velocity and acceleration equations are formulated such that the relevant analysis can be integrated under a unified framework that is based on the ...

3DoF Model Helicopter with Hybrid Control
TELKOMNIKA Indonesian Journal of Electrical Engineering, 2014 Dynamics of miniature unmanned helicopter are considered nonlinear and mutually coupled; therefore designing of a stable control becomes a big challenge for researchers. This paper addresses this issue by proposing a hybrid control methodology using both traditional and intelligent control.
