Position control of single stage dual range positioning system

High speed machines with high positioning accuracy have become very important in order to achieve high productivity gains. The system that is capable of achieving both coarse and fine positioning has a wide range of applications in the field of precision engineering. This paper presents a novel method for position control of single stage dual range actuation system. In the developed system both coarse and fine positioning is achieved using ball screw actuator and a gearing mechanism. The friction in the ball screw actuator is identified using Tustin and LuGre models. Position control of the developed system is programmed using Programmable Logic Controller.
