Control of high-rise/high-speed elevators

Abstract

An analytical framework for the development and evaluation of motion control system concepts for high-rise, high-speed elevators is presented in this paper. This problem definition, which includes a discussion of typical control system performance requirements, plant model dynamics and uncertainties, and control system robustness requirements, serves as a benchmark for the application and evaluation of advanced control approaches. Unique features of this problem include time varying dynamics, uncertain structural response, noncolocated control, sensor suite selection, and separable command and disturbance rejection control system requirements.
