Course description and aims

This course covers the fundamentals of linear system theory based on state equations, and shows how to analyze systems and how to design controllers for them. In the system analysis, stability, controllability and observability are introduced. In the controller design, state feedback controllers (pole assignment and optimal control), observers and servo controllers are introduced.

The state equation is one of the system descriptions, and many kinds of systems can be described in state equations, for example, mechanical, electrical, chemical and economical systems. This course not only shows how to analyze and how to control systems, but also shows their theoretical background, which is necessary knowledge for developing new system theory.

Student learning outcomes

At the end of this course, students will be able to:

1) Analyze the stability, controllability and observability of the system.
2) Design stabilizing controllers.
3) Have an understanding of mathematical derivation of the theories, and acquire the ability to develop new system theory

Keywords

Linear System Theory, Linear Control Theory, State Equation.

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

The first two thirds of the course concentrates on how to use theories. The remaining one third of the course gives the detailed mathematical proof of the theories.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

Textbook(s)

All materials used in class can be found on OCW-i.

Assessment criteria and methods

Students' course scores are based on the reports (100%).

Students will be assessed on their understandings of system analysis (controllablity, observability, etc.) and controller design (state feedback, observer, etc.), and their ability to apply them to solve problems.
