ACTIVE DAMPING GUIDE ROLLER DESIGN BASED ON INTEGRATED STRUCTURE/CONTROLLER OPTIMIZATION WITH A STRUCTURED CONTROLLER

摘要

In this paper, the integrated structure/controller optimization has been applied to design the active damping guide roller to suppress the elevator lateral vibration. The guide rollers and their corresponding controller are considered as the design variables, simultaneously. And the weighted sum of the suspension deflection, the elevator's acceleration and the control force are regarded as optimization functions to be minimized. Because a structured controller is used, this optimization problem can be solved by Genetic Algorithm directly. The control scheme is validated for a scaled elevator in the lab. The numerical results show that the integrated structure/controller design can provide an alternative method to achieve better ride comfort with a "sky-hook" damper controller compared to the sequential design.
