摘要
为了消除驱动喷管摆动的2个作动器间的牵连效应,确保控制指令精确,利用旋转矩阵原理,计算喷管摆动时2路作动器的伸长量,进一步设计出用于前摆心深潜入式喷管的摆动控制系统。试验结果显示,4°单摆时牵连摆角占最大摆角比值较大(7.15%),补偿计算后最大牵连摆角仅为0.002°,从而验证了该方法能通过消除牵连效应提高全轴摆动喷管的控制精度。
In order to eliminate the coupling effects between two actuators driving the nozzle swings, as well as to ensure the precision of control command, the elongation of the two actuators was calculated when the nozzle swung based on the principle of rotation matrix.Further the swing control system for deeply submerged nozzle with front pivot point was designed.The experiment results show when angle of one-way swing reaches 4 degrees, the large ratio（ 7.15% ）between the coupled angle and maximum swing angle exists, the maximum coupled angle is 0.002 degrees only using compensation calculation, and the control precision of the omniaxial movable nozzle through eliminating the coupling effects can be improved greatly by the method proposed in this paper.
