Laboratory Model of an Elevator: Control with Three Speed Profiles
Sažetak
In this article a control of laboratory model of an elevator with three different driving speeds is described. Physical model that simulates the elevator consists of an elevator car driven with small DC motor, track with 6 mechanical switches used for position of an elevator car and control section: speed, direction and safety relays with Siemens PLC S7-300 as a main control device. The purpose of this type of control is to show the use of a different speed profiles for simulation of comfort elevator ride.
