The second general class of servo control addresses the disturbance rejection characteristics of the system. Disturbances can be anything from torque disturbances on the motor shaft to incorrect motor parameter estimations used in the feedforward control. The familiar “P.I.D.” (Proportional Integral and Derivative position loop) and "P.I.V." (Proportional position loop Integral and proportional Velocity loop) controls are used to combat these types of problems. In contrast to feedforward control, which predicts the needed internal commands for zero following error, disturbance rejection control reacts to unknown disturbances and modeling errors. Complete servo control systems combine both these types of servo control to provide the best overall performance.

We now examine the two most common forms of disturbance rejection servo control, P.I.D. and P.I.V. After understanding the differences between these two topologies, we then investigate the additional use of a simple feedforward controller for an elementary trapezoidal velocity move profile.

The basic components of a typical servo motion system are depicted in Fig.1 using standard LaPlace notation. In this figure, the servo drive closes a current loop and is modeled simply as a linear transfer function G(s). Of course the servo drive will have peak current limits, so this linear model is not entirely accurate, however it does provide a reasonable representation for our analysis. In their most basic form, servo drives receive a voltage command that represents a desired motor current. Motor shaft torque, T is related to motor current, I by the torque constant, Kt . Equation (1) shows this relationship. T ≈ Kt I (1) Page 2 of 11 For the purposes of this discussion the transfer function of the current regulator or really the torque regulator can be approximated as unity for the relatively lower motion frequencies we are interested in and therefore we make the following approximation shown in (2).
