Abstract

In this brief, we study the problem of rope sway dynamics control for elevator systems. We choose to actuate the system with a force actuator pulling on the compensation sheave. Under these conditions, we formulate this problem as a bilinear control problem and propose several nonlinear controllers based on Lyapunov theory to stabilize the rope sway dynamics, for different elevator operation conditions. We present a stability analysis of the proposed controllers, and illustrate their performance via numerical tests.
