Course description and aims
Control Engineering is decomposed into three topics, i.e., mathematical modeling, system analysis, and control system design. This course treats the first two topics among these topics. In particular, the mathematical modeling in the first half of this course includes topics on state equations and transfer functions of dynamical system, which are mathematical models suited for the control design, and further Euler-Lagrange motion equations for deriving the state-equations. In the second half, as a part of the system analysis, students learn how to analyze system behavior such as transient/steady-state responses and the stability of dynamical systems from the perspectives of time responses.
The aim of the course is that students will have the basic knowledge on control engineering, including state equations/transfer functions, system response and stability, to understand control system design theory based on state equations and transfer functions of the systems.
Student learning outcomes
By completing this course, students will be able to:
1) Understand the outline of control engineering.
2) Derive a state equation/transfer function based on mathematical models such as equations of motion for a given controlled plant of mechanical systems and electric circuits.
3) Analyze time responses of dynamical systems such as transient response and stability.

Class flow
Basically, writing on the blackboard and explaining are taken turns. It is very important to make your own notes, which can provide systematic knowledge on modeling and analysis of dynamical systems at the end of this course. 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.
