The research of real-time test of brake-by-wire system for aircraft using HILS & dynamometer system

In this paper, it Is a study to valid a compatibility of digital control unit (DCU) for an aircraft brake system through a dynamometer test as well as HILS test It is very important because results of this test are satisfied before installing on an aircraft. The dynamometer system is composed of dynamo, HILS (hardware-in-the-loop-simulation) and velocity sensors installed on wheel and dynamo. The DCU was tested under various friction conditions in HILS and dynamometer test. The DCU with ABS control algorithm protected very well a wheel skid on high friction condition as well as low friction condition.
