Abstract: Servo system is a crucial part of the radar to realize the realtime capturing and tracing ob jects.Precision tracking radar servo is composed of three feedback control loops.There is high precision and quick dynamic response in it. In this paper, pointed out the design process and methods of the servo system current loop, speed loop and position loop with the practical application, established a mathematical model of the loop, and simulation. It has a certain reference on the other servo system design. Key words: servo system;current loop;speed loop;position loop; PWM power amplifier; transfer function
