초록
A tracking radar for ships is a sensor linked to a CFCS to acquire and track the main target designated from the search radar. The director part of the tracking radar consists of a subsystem and servo system for target orientation. To reliably track the designated target using a tracking radar, the stability of the 0.Xmrad (rms) must be maintained. To maintain the stability of the servo system, parameter estimation through system modeling was used to set the notch filter required to remove the resonant frequency to ensure stability. For target-oriented stability of the tracking radar, the resonance of structures such as motors and reducers must be examined. In this study, the stable operation of the tracking radar director and frequency response characteristics of the control system using a servo motor were considered, and the results of stability confirmation after setting the effective controller parameters were presented.
