This work presents a complete procedure of the closed-loop control system tunning for the electric drive with a two-mass flexible actuator. The Welch method and frequency analysis are used for the plant’s parameter identification. The feedback compensator based on the time derivative of the acceleration is designed to compensate for the plant oscillations. https://www.spidertattooz.com/SQB-PROTON-QUAD-M4-MAG-POUCH-INSERT-SMOKE-GREY/
