In reality, the user never wants to put a step command into their mechanics, unless of course the step is so small that no damage will result. The use of a step response in determining a system’s performance is mostly traditional. The structure of the P.I.V. control and for that matter, the P.I.D. control is designed to reject unknown disturbances to the system. Fig.1 shows this unknown torque disturbance, Td as part of the servo motor model.

Disturbance Rejection Characteristics

If we consider the case where the motor is holding a final position and an unknown disturbance at some frequency is applied to the motor shaft, can we predict how the shaft will respond? To graphically quantify the effect of the P.I.V. gains on this disturbance torque, disturbance rejection plots are drawn showing the magnitude of disturbance needed at a given frequency to result in a specified shaft motion. Fig. 5 illustrates the two cases of constant damping and varying bandwidths (Fig. 5a) and constant bandwidth and varying damping

In Fig. 5a) the low frequency rejection gain increases as the bandwidth value goes up. Notice for high frequency rejection, only the motor’s inertia is effective regardless of the bandwidth of the servo controller. This is why users occasionally request "high inertia" motors even at the expense of requiring more overall torque to make their move. A similar disturbance rejection trend is seen in Fig. 5 b). Here, the mid-frequency rejection gain increases slightly as the damping ratio is raised.
