Performance Robustness Analysis via Root Clustering (Robust D-Stability)

  • Rama K. Yedavalli


In this chapter, we address the issue of performance robustness, in contrast to stability robustness discussed in the previous chapter. We assume that “performance” of the control system is characterized by speed of response which in turn is a function of the location of the eigenvalues of the closed-loop system. Thus, we treat the performance robustness problem as robust D-stability problem where the D-stability region is a subregion in the complex plane.
