Abstract：The development status of multi-axis synchronization control structure and algorithm was analyzed. To solve the problem that equal state coupling control in practical application, the proportion coefficient distribution method based on normalization is proposed for multi-axis proportional synchronization control, and an improved cycle-coupling control strategy was designed on this basis. The convergence and stability of which are proved by use of Lyapunov function. Take the flexible nozzle as control plant, its models of terminal actuator electric cylinder and contour control system are established. The simulation results show that the proposed strategy has better synchronized stability behavior and robustness than Virtual-Shaft control. The experiment results that through contour control system of trans-supersonic wind tunnel also show that the proposed strategy can effectively achieve multi-axis proportional synchronous control, has higher tracking precision and synchronous precision, and also has a certain reference value to related field.
