Active control system for suppressing swing and sway behaviors of engineering structures or mechanical systems

Abstract

An active control system for suppressing swing and sway behaviors includes a first motor, a rotating plate, a sensor and a controller. The first motor is provided on a to-be-controlled object. The rotating plate is provided on the first motor. The controller is connected to the sensor and the first motor. The sensor is configured to detect a torsional angle of the to-be-controlled object and send the torsional angle to the controller. The controller is configured to process the torsional angle and output a control instruction to the first motor based on a processing result, so as to control the first motor to drive the rotating plate to rotate.
