Abstract

Most stage directors and designers make use of controling and moving lots of stage set or device as a large automation device or machine to achieve dramatic effect in their performances. Specially, it is very important to use a programmable multi-chain hoist system which is able to move high speed as well as to lift heavy loads. This paper proposes a multi chain hoist servo system to lift or lower a heavy load of about l ton for public performances' stage. It is automatically operated, electrically driven by a control console with a PTP trajectory generation algorithm, a realtime network control algorithm, and 4 step sequential safety algorithm. The efficiency and performance of the developed system are verified through a series of experiments.
