To solve the problem that the existed algorithms which based on the virtual shaft control principle are difficult to meet the requirements of the proportional synchronized control in some object contouring system, an improved virtual shaft structure was proposed, which can apply to completely synchronized and proportional synchronized of multi-motor control system. Introduce the construct of the improved virtual shaft, aiming at its characteristics and with the applying background of the full flexible nozzle contour control system in the trans-supersonic wind tunnel, coefficient of proportionality assignment algorithm was designed and the synchronized control simulation mode of four electric cylinders was set up. Simulation results show that the control scheme has a quick convergence rate, good stability behavior and strong robustness, which can effectively achieve multi-motor proportional synchronous control.
