Lab View Based Virtual Instrumentation and Control System for Testing of Linear Hydraulic Actuator

Linear hydraulic actuators for critical applications, have to undergo very stringent qualification tests, to establish their suitability for the designed task. Endurance test is one of the important tests conducted on linear actuators, as a part of design qualification. The endurance test requirements are very stringent, and hence conducting the test manually is very tedious and time consuming. The paper describes a PC based Virtual instrumentation and controller developed for one such application.
