Design and Implementation of High Precision Electric Control Rail Applied in Dynamic Tracked Aiming

A high precision electric control rail used for ground aiming system was manufactured. Special electric machine drive circuit and controlling algorithm based on AVR Atmega128 as core processor were designed in the rail, achieving high positioning precision, high linearity, and high resolution, with characteristics of large stroke, stable operation, and fast respondent. The result of the practice was proved that the rail could work well with the collimator to remote track the prism, assuring the accuracy of automatic aiming and improving the efficiency of the automatic measurement to the rocket initial attitude.
