Robust model-following control for the DC servo drive

The goal of this paper is to present a new method that ensures stiffness of the mechanical characteristic of the direct current motor servo drive, which means lack of influence of the varying load torque on quality of the velocity control. Additionally, usage of the new MFC-V system allows one to shape the servo drive transient response, ensuring, among other things, an overshoot free step response in the velocity control loop. The proposed solution exemplifies a possible approach to designing a DC motor servo drive of a CNC power transmission system.
