1.1 Introduction to Automatic Control Automatic Control Systems permeate life in all advanced societies today. Technological develop- ments have made it possible to travel to the moon; explore outer space. And

(P173)In this section the concepts outlined previously will be developed further into some straightforward guidelines for plotting more complex root loci, which will be f llustrated by focusing on a specific example Root locus: (review of previous lecture)

13.1 Conformal Mapping: Cauchy's Theorem (保角映射:柯西定理) Recall Stability Problem: To determine the relative stability of a closed-loop system we must investigate the characteristic equation of the system

Plot the bode diagram of a complex system Write the transfer function of system through the bode diagram

Module 3 First Order System (1 hours) First order systems .Time response of first order systems .Proportional feedback control of first order systems

Module 5 Second-Order System Time-Domain Response (2 hours) Ramp response Harmonic response Transient response as a function of the location of the poles

Module 7 Higher -Order Systems (1 hour) TF in Evans or Bode form Approximate a higher order system with a first or second order one Effect of zeros and poles on the transient response Origins of zeros
