The paper presents a method of synthesis of servo driver for controlling the speed of the object with the speed tuned at the modular optimum. An automatic electric motor drive is considered as the controlled element. This assumes the use of the speed sensor on the output shaft of the drive gear. This approach can be used for geared motors, which are more commonly used in a variety of compact drives. The technique is based on the method of synthesis by using logarithmic frequency response (LFR). The result is a synthesis of the two tracking angle controllers: proportional-integral and proportional-derivative (PIPD regulator). The criterion for the synthesis of tracking angle controller is the desired LFR, the characteristics of which are defined based on saturated capability transition function of controlled object with standard configuration for modular optimum. It is assumed that the maximum speed and acceleration of the transition functions are required for the synthesis of parameters of servo driver system by LFR. The article covers the accuracy and contains an example of a particular electric motor.
