Course Description

Design and digital implementation of multiple-input, multiple-output (MIMO) linear feedback control systems for specified dynamic response; z-transform and sampling; exposure to embedded control systems; state-space based models; introduction to advanced concepts of multi-variable control. Design and implementation project on real-time digital control.

Objectives

  • To build on students’ undergraduate exposure to feedback control and teach advanced design techniques
  • To impart knowledge of practical issues related to the implementation of feedback controllers using digital processors.
  • To introduce advanced techniques of linear multivariable control system design.
  • To expose students to aspects of embedded control systems as practiced in robotics, automotive, aerospace, process industries.
  • To prepare students for advanced courses in mathematical control theory and practical control engineering.

Learning Outcomes

  • Identify state, measurement and control in a given problem.
  • Design controllers for linear models of systems using MATLAB and SIMULINK.
  • Select and program real-time digital controllers on platforms similar to PC, microcontroller, DSP.
  • Predict performance for complex multivariable control tasks.

Pre-requisites

EE-361. Feedback Control Systems

Text book

The course will be taught from the following textbooks.

  • FranklinF. Feedback control of dynamic systems by Franklin, Powell and Emami-Naeni (5th edition), Pearson, 2006.
  • FranklinD. Digital control of dynamic systems by Franklin, Powell and Workman (3rd edition), Addison Wesley, 2000.

Other important references include

  • Astrom. Computer controlled systems by Karl Astrom and Bjorn Witternmark, Prentice Hall, 1997.
  • Oppenheim. Signals and Systems by Oppenheim, Wilsky, Nawab (2nd edition), Pearson, 1997.

Grading Scheme

Homeworks+Quiz : 15%

Project: 20%

Midterm: 30%

Final : 35%

Policies and Guidelines

  • Quizzes will be announced. There will be no makeup quiz.
  • Homework will be due at the beginning of the class on the due date. Late homework will not be accepted.
  • You are allowed to collaborate on homework. However, copying solutions is absolutely not permitted. Offenders will be reported for disciplinary action as per university rules.
  • Any appeals on grading of homeworks, quiz or midterm scores must be resolved within one week of the return of graded material.
  • Attendance is in lectures and tutorials strongly recommended but not mandatory. However, you are responsible for catching the announcements made in the class.
  • Many of the homeworks will include MATLAB based computer exercise. Some proficiency in programming numerical algorithms is essential for both the homework and project.
