Control Systems IΙI

General

Course Contents

Introduction to controller design : Basic specifications in the time domain. Types of controllers-compensators. Categories of control problems. Closed loop block diagrams with different configurations. Effect of disturbances, noise and sensitivity functions. Basic design tools (Root locus, Bode diagrams). Root locus design. Phase lead/lag compensators. Two and Three term controllers (PI,PD,PID). Frequency domain design techniques. Pole placement design techniques. Exercises and applications in MATLAB.

Educational Goals

The aim of the course is to provide an introduction to the process of designing continuous time compensators/controllers so that given specifications are met. Various synthesis techniques, analytical and graphical, are presented using both mathematical models, i.e. transfer function and state space. Various types of controllers (series, feedback and input) and combinations of them are studied. Empirical techniques are also presented, in case the mathematical model of the system is not available. Consistent and successful attendance of the course has as expected result to make the student competent:
– to design compensators of different types (series, input, feedback or a combination thereof) to meet given design specifications / objectives with different techniques, with any mathematical model, or even when the mathematical model is not available;
– confirm the design by simulation in MATLAB / SIMULINK environment;
– implement compensators with active or passive elements and face the practical difficulties and limitations that arise.

General Skills

Research, analysis and synthesis of data and information using corresponding technologies, decision making, adaptation to new situations, Promoting free, creative and inductive thinking, independent work, Teamwork.

Teaching Methods

Lectures, Exercises, Online guidance, Projected Presentations, E-mail communication, Online Synchronous and Asynchronous Teaching Platform (Moodle).

Students Evaluation

Assessment Language: English / Greek
The final grade of the course is formed by 80% by the grade of the theoretical part, and 20% by the grade of project work.
The grade of the theoretical part is based on a written final examination.
The written final examination of the theoretical part may include:
Solving problems of application of the acquired knowledge, Short answer questions etc
