摘要：

Current control loop Bode diagrams of servo drives are commonly used for electrical resistance and inductance identification. Apart from these parameters the Bode diagrams contain the information on the total delay time of the loop. The study considers identification of this delay, the value being important during the development stages for proving the servo drive is functioning properly as well as for preliminary parameter setup. In the paper a robust algorithm for current control loop identification is proposed. Theoretical evaluations are proved by the simulation and experimental results obtained from a servo drive with coupled to a 3 level inverter implementing two different PWM strategies.
