Design of an acceleration rate controller for a linear drive of a vertical transportation system

In this paper a control system with an acceleration rate controller for a linear drive of a hoisting system is presented. The control system consists of a closed-loop speed control with an inner acceleration rate control loop and current control loop. A simulation model established for the analysis and optimization of the system is described and verified. The control parameters derived from the simulation are implemented on a model of the hoisting system equipped with the linear drive. The driving performance of the linear drive with acceleration rate controller is compared to a more simple controller structure with closed loop speed control and inner current control loop.
