Bionic control method for stable tracking of semi-strap-down seeker

In the process of tracking and capturing the targets of semi-strap-down seeker, the ordinary control method divides the stabilization and tracking task into two seperate parts with independent cotnrol laws. In contrast, flying insects tend to counteract the body rotation and the relative translation of the pray and predator by head rotation, in order to keep the target in the field of view. According to this predatory behavior mechanism, this article designed a semi-strap-down seeker with bionic control method for both optical-axis stabilization and target tracking. This method can isolate the missile motion and reduce the tracking error angle, so that the optical axis is approximately coincident with the line of sight (LOS).
