Hardware-in-loop Simulation System for the Disturbed Movement of Hose-drogue During Aerial Refueling

A novel hardware-in-loop (HIL) ground experiment system is proposed in this paper where the corresponding movement of drogue under external interference can be realized according to the digital simulation results obtained from Matlab. The whole system is composed of simulation subsystem modeled by multi-rigid-body dynamics, two-dimensional moveable platform, human-machine interface and motion control system. Data stream from Matlab to industrial computer is transferred by ethernet with UDP protocal and PCI–1245E is employed to transform position data to impulse signals for the sake of driving the servomotor. Experimental results manifest that effectiveness of hardware-in-loop ground experiment system where accurate motion of drogue in relation to simulation results can be achieved with high real-time performance.
