Coaxial Control of Injection Equipments by Master Slave Scheme for a Parallel Speed Control System

Abstract

In this paper, a novel master-slave system is proposed for the coaxial control of injection equipments constituted with two or more drive axes. Each drive axis is basically controlled by the PI speed control system and a new master-slave scheme is introduced for the tracking control of the angles of the two parallel subsystems. The adequacy of the scheme is supported by the controllability of the system. Easiness of the parameter tuning of the controller is clarified from the viewpoint of stability, tracking property, and disturbance rejection property. Simulation result and experimental result are also given for the test equipment.
