| Abstract: | In order to solve the problem of three actuator moving out of sync in the control of aeroengine axial-symmetric vectoring exhaust nozzle, two kinds of actuator loop coupling control schemes were designed for vectoring nozzle control based on synchronous control theory, and the loop coupling control scheme of varying electric current based on error proportion was analyzed and verified by digital simulation and semi-physical simulation test. The results show that the loop coupling control scheme of varying electric current based on error proportion realizes three actuators moving synchronically and ending at the same time in certain deflection angle and azimuth, and the vectoring control is steady and safe, which has excellent performance on response speed and accuracy. |
