## Ph.D. Thesis- Local Analysis of Perturbed Linear Systems with Application to Saturating Control Systems
*PhD Thesis, Stanford University, EE Dept., March 2000.* The goal of this thesis was to develop a set of tools for computing guaranteed regions of attraction, bounds on L_2 disturbance rejection and on L_2 gain, for linear systems perturbed by sector bounded nonlinearities, in particular, saturation nonlinearities. This allows more daring and better specified designs. Efficient Linear Matrix Inequality (LMI) global analysis techniques were extended to the problem of local stability and performance analysis. The issue of computing optimal Lyapunov functions for local analysis was addressed and used to point out the advantages and limitations of the new techniques. The result is a set of tools that are: computationally efficient, simple to implement, easy to understand, not overly conservative, able to handle multiple saturation nonlinearities and both continuous- and discrete-time systems. Two applications for the tools are presented: control systems with saturation, and distortion analysis in power amplifiers with saturation.
