Course description and aims

I Electrical Engineering students are provided with fundamentals in classical control theory. Control theories are provided in their entirety along with automatic control theory, which is modern control theory.
II Introduction, transfer function, 1st order lag system, 2nd order lag system, block diagram, transient response, vector trajectory, bode plots, stability, steady state characteristics, step response, complicated bode diagram, controller, proportional controller, proportional and integral controller, proportional and derivative controller, PID controller

Student learning outcomes

The main purpose of the lecture is to obtain design ability of controllers based on classical control theory as below,
The gains of PID controller can be determined with a help of bode plots.
The steady state errors can be estimated.
Rough waveforms of step reseponse can be drawn by free hand.

Course taught by instructors with work experience

✔ Applicable How instructors' work experience benefits the course
The lecture was an experience to develop PI controller for speed feedback system in motor drive. In addition, he also developed PID controller for manetically suspended system. The design of PI and PID controllers are the main subject of this lecture.
