EXPERIMENTAL SYSTEM DESIGN AND SIMULATION
STUDY ON ATCIVE CONTROL OF LATERAL VIBRATION
FOR HIGH SPEED ELEVATOR

ABSTRACT

In recent years, the high-speed elevator is used more and more
widely with the continuously increasing of high buildings. But with the
increasing of elevator speed, the elevator vibration will be expanded
distinctly, which will deteriorate severely fortness of elevator. So
vibration control es a more and more noticeable problem for
high-speed elevator. With the development of modern control theory, the
active control has e the chief way to control lateral vibration of
elevator.
The thesis introduces the experimental system design and the
simulation of active control for elevator’s lateral vibration.
Firstly, according to the experimental scheme, the vibration
differential equation and math model with right-to-left vibration. And
analysing the free frequency speciality of lateral vibration and
simulating the lateral vibration acceleration response in the
MATLAB/SIMULINK.
Then according to the scheme, designing specially the experimental
system, including the model of elevator frame and car, the system of

And using the experimental system to conduct the free vibrations and
forced vibrations test.
