Abstract In wind-tunnel test, it is a new trend to control the leading edge of aircraft model for dynamic test, and also for special experimental research. Based on the principle of the CNC servo for X-Y table circular interpolation, a new leading edge controlling system is proposed. The control parameter of the system is modified after simulation and analysis, so that the error is reduced and the practical motion trajectory of leading edge maximumly approaches the instruction trajectory. The result of wind tunnel test shows that this system is feasible and has high accuracy.
