High speed elevator dynamic analysis and control on severe conditions
(2020-01-01)
The advent of verticalization after WWII made the densification on major cities. Thus the high-rise building was the solution to accommodate the vast amount of people on cities. The elevator was a solution to vertical ...
On the controllers' design to stabilize ground resonance helicopter
(2019-12-01)
Ground resonance (GR) in helicopters is a potentially catastrophic instability commonly caused by coalescence of the regressive cyclic blade lag mode with the fuselage motion in certain rotor speed ranges. It can limit the ...
Variable Speed Control Moment Gyroscope in an Inverted Pendulum
(Asme, 2019-11-01)
The use of variable speed control moment gyroscope (VSCMG) is an effective way for attitude stabilization of aerospace devices. It is possible to control the oscillation and direction rate of change in rigid bodies in space ...
