This book is a self-learning guide to MATLAB based Control System design. It is written in a lucid way so that any of the control system or MATLAB beginner can confidently use it. This is an ideal book for the control system courses in undergraduate and poly-technic level. It is divided into two sections viz an introduction to MATLAB, and control system simulation using MATLAB. The first section gives an introduction and basic concepts on MATLAB. The second section is a tutorial for control systems and its MATLAB implementation. Bode-plot, Root-locus, Nyquist plot and Nicholas plot have been discussed at the simplest level and step-by-step methods to plot them are elaborately discussed.Other distinguished features of this book include State-space analysis and transient response analysis using MATLAB. A large number of solved numerical problems and exercise problems are given at the end of each chapter.
