Looper System

Abstract The looper system, located midway between adjacent stands, is a mechanical levitation device commonly applied on modern hot strip mills. In order to fully understand factors affecting the looper’s behavior and predict its motion during rolling processes, a comprehensively mathematical simulation model of the looper control system for a hot strip tandem mill is developed. The simulator includes three system modules: the looper regulator module, the looper dynamics module, and the mass flow module. Simulation results demonstrate good compatibility with position measurement of real rolling processes. Looper responses under circumstances of different original strip lengths and a varying roller speed are specifically examined. Based on this looper simulator, valuable information can be easily obtained for possible improvements on rolling processes in the future.

Arbitrary Trajectory

In this paper, a nonlinear control of a tilting rotor quadcopter is presented. The overall control architecture is divided into two sub-controllers. The first controller is based on the feedback linearization control derived from the dynamic model of the tilting quadcopter. This controls the pitch, roll, and yaw motions required for movement along an arbitrary trajectory in space. The second controller is based on two PD controllers which are used to control the tilting of the quadcopter independently along the pitch and the yaw directions respectively. The overall control enables the quadcopter to combine tilting and movement along a desired trajectory simultaneously. Simulation studies are presented based on the developed nonlinear dynamic model of the tilting rotor quadcopter to demonstrate the validity and effectiveness of the overall control system for an arbitrary trajectory tracking.
