摘要
Abstract
The compensation of the throat area accuracy for the axial-symmetric vectoring exhaust nozzle (AVEN) by the control compensation system is studied.The kinematic and inverse kinematics models of throat are established.The precision of the throat is analyzed by considering the effect of the machining error,input error and the gap error of the hinge.The Open-loop inverse mode control and mononeuric PID & inverse mode feedforward control are used to design the control compensation system to realize the compensation of the precision of the throat area.The method of simulation test shows that the latter has better compensation effect on the throat area.With the system compensation,deviation of throat area is less than 1％,which provids important reference for the precision and compensation control of the axial-symmetric vectoring exhaust nozzle.关键词
