ADAPTIVE PI CONTROL SYSTEM.

摘要

An adaptive proportional integration control system for controlling a robot or a machine tool having large load fluctuation. This PI control system includes a speed control loop and a pre-compensator (31) disposed in the speed control loop. The pre-compensator is equivalent to a system formed by coupling a norm model (51) and an inverse system (52) of a servo motor (22), and has adaptability. Since the pre-compensator (31) is disposed in the speed control loop, robust control can be made even when inertia of a load drastically fluctuates.
