Part 1: Phase Lead Controller Design 30%
Design a suitable phase-lead controller. You should explain in detail how your design has been developed. Your solution should include Bode plots constructed both manually and using an appropriate package such as MATLAB or Scilab. (20%) Using the design rules in the Control Engineering Data Sheets, obtain the TF of the “equivalent” 2nd order TF (including controller). (5%) Compare the unit step responses of the equivalent 2nd order TF and the actual closed loop system, and comment on the accuracy of the equivalent. (5%)
Part 2: Digital Controller Implementation 35%
Using the phase lead controller transfer function obtained above as a prototype, design a digital controller using Bilinear Transform or any other method of your choice (10%) Select a….
