| Outline of Final Research Achievements |
As a result of this research, current harmonics that are a problem in electrolytic capacitorless inverters are suppressed by the direct DC link current control method, and viscous friction on the drive side is controlled by the drive side nominalization compensator, shaft torsion torque, and differential speed feedback. Realized back drive control. As a result of evaluating the proposed system by experimental verification using HILS, the increase of torque pulsation is suppressed by combining the inverter without the electrolytic capacitor and the direct current control of the DC link, and the vibration of the system response is reduced. From the above, we have realized a control system that can back drive an AC servomotor using a single-phase three-phase inverter without an electric field capacitor.
