Abstract: In this paper, a novel anti-sway control system that uses an inclinometer as a sway sensor is investigated. The inclinometer, when compared with a vision system, is very cheap, durable, and easy to maintain, while providing almost the same performance. A number of observers to estimate the angular velocity of the load and the trolley velocity are presented. A state feedback controller...

This paper describes the control system for innovative air-conditioning equipment, in particular an air treatment unit. The most important characteristic of the equipment is to be “friend of the environment”, in the sense that it does not use environmentally aggressive refrigerating fluids. Other main characteristic is associated with the complexity of its control, due to the large number of in...

Many firms within the high technology capital equipment sector are faced with a situation where effective inventory management is a rather complex and possibly most critical factor to their long-term profitability. Within this thesis we discuss the development of two decision support tools that address some of the unique aspects of the situation faced by Teradyne, Inc., one of the largest suppl...

A message oriented software scheme is used for the SPring-8 beamline control [1]. In the early stage, we developed customized control programs for each beamline. As the number of beamlines increased, however, it became necessary to introduce a general software scheme that could handle the control sequence for every beamline. We developed a new server program, Command Interpreter (CI), as a soft...
