The high precision motion control of aircraft model supported by a sixDOF wiredriven parallel robot in the application of wind tunnel test wire is studied in this paper. Firstly, in view of the possible interference between wire and aircraft model, based on the concept of timevariant wire system, a kind of timevariant kinematic equation is designed. And the dynamic equations of the driven system and aircraft model are then established. Secondly, according to the constructed system dynamic model, a proportional and differential controller is proposed on the base of pose feedback, and the stability of the closedloop system is analyzed. Finally, numerical simulations of timeinvariant and timevariant systems are developed as the examples of singleDOF and multiDOF motion. The analysis results show that the built mathematic models are appropriate and practicable, and a singleDOF time variant system can effectively avoid the pitch motion interference. Meanwhile, the proper selection of wire pretension can keep the wire from slackness. Furthermore, a PD control law with interference compensation term realizes the aircraft′s high precision motion control, accordingly to meet the application requirements of wind tunnel test.
