Virtual Power Limiter System which Guarantees Stability of Control Systems

Abstract

In this paper, a Virtual Power Limiter System is proposed. This requires no modeling and makes it possible to guarantee the stability of control systems which include unknown characteristics: flexibility in flexible manipulators, compressibility in pneumatic servo systems, human dynamics in man-machine systems, hardware nonlinearity in mechatronic systems, and so on. The details of the proposed virtual power limiter system and experimental verification with a man-machine system are presented.
