In order to realize the full digitalization and miniaturization of the ship-borne antenna servo system, a fully digital inner loop design method can be used to adjust the digital PID parameters through DA or AD conversion between signals. Large scale integrated circuits, such as PWM pulse width modulation amplifiers, can be used to achieve the desired antenna motion and response characteristics and achieve the acquisition and tracking of space targets and command control. The digital design scheme proposed below is simple, stable and reliable, and has certain universality.
