Hybrid system is a dynamical system composed of discrete-valued variables and continuous-valued variables. It is also defined as a dynamical system composed of logical variables and physical variables. This includes control systems with logic operations and ON-OFF switches, discontinuous physical phenomena such as jump behavior. This course focuses on such systems, and covers the fundamentals on hybrid system representation and control design methods.
The aim of this course is that students who have already learned classical control theory and modern control theory will learn, as an advanced control theory, how to represent logical systems such as an automaton, and how to combine the logical system model and physical system model as a hybrid system model, and then how to design a model predictive control of the hybrid system model.
At the end of this course, students will be able to:
1) Explain the concept of hybrid systems composed of discrete-valued variables and continuous-valued variables.
2) Derive a hybrid system model expressing complex system behavior in a form being suitable to control design.
3) Design a model predictive controller based on hybrid system models.

The first 60 min. of each class includes the lecture on topics, and the other 40 min. includes exercise problems related to the lecture given that day.
To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.
