This presentation describes the design and implementation of a CompactRIO and LabVIEW Real-Time based digital controller for active control of the position of a steel ball on an inclined ramp. The system employs an electromagnet as an actuator and a non-contact, optical ball position sensor . Presented to the Orange County LabVIEW User Group Meeting on Oct 29, 2009. The companion video below shows the system in action.
