Abstract

The paper details the characteristics of a single axis actuator control system, capable of conducting tests via both displacement and load control method. The scalable actuator control system or SACS, was developed at the University of Dundee to match the increasing complexity involved in motion control and load sequences during model tests in the centrifuge. The module has a single PID controller driving a single axis with provision to future expansion, a waveform generator and sequence controller; which are operated within a single intuitive user interface, LABVIEW. The interface allows a seamless switching between automated and manual control, resulting in simultaneous automated control of the actuator in load and/or displacement control.
