摘要
三框架四轴平台系统的随动回路依靠控制随动框架转动使内环框架角始终保持在零位附近,用以保证载体在内环轴方向上具备全方位机动的能力。然而当外环框架角工作在±90°附近时,随动回路会失去正常功能,进入不稳定状态。为了解决这个问题,提出了一种新的随动框架控制方案,保证外环框架角在±90°时随动框架处于稳定状态,同时内环轴所指方向仍然可以进行大范围机动,从而使得三框架四轴平台实现真正的全方位机动能力。
The follow-up loop of four-axis inertial platform can track inside frame axis that make inside frame holding zero position. Thus, the missile can make omnidirectional movement along inside frame axis. When outside frame axis gets to ±90° position, follow-up loop won't work. So we could not say that the missile can do omnidirectional movement along outside frame axis. The paper-describes a control method for follow-up frame that can make missile do omnidirectional movement along outside frame.
