The objective of modeling the damping controller is to enhance the damping ratio of the poorly-damped or unstable electromechanical modes of oscillation, which can be achieved through designing of a damping controller that provides a pure damping torque.
The damping ratio should be plotted as a function of driving speed.
To obtain a smoother response, a default virtual mass is chosen by applying a safety factor to the minimal virtual mass to virtual damping ratio.
