Abstract
Disturbance rejection is an important factor in the synthesis of controllers for several practical systems. In this chapter we derive necessary conditions which need to be satisfied by the controller which yields maximum disturbance rejection. Necessary conditions for maximum disturbance rejection are also derived in the case of an observer-based controller. These conditions are useful in the synthesis of a controller which maximizes the disturbance rejection capacity of the system. The problem considered has connections to the H ∞ control theory. An example is given.
