Course title
Introduction to Control Engineering

ITO Kazuhisa
Course description
This course provides fundamentals of the control engineering including some mathematical preliminaries, which is applied to various automation devices. The main topics of the class are Laplace transforms, transfer functions, transient characteristics, block diagrams and frequency characteristics. To complete this course, it is necessary to check some basics of physics and calculus including simple linear differential equation.
This course is a prerequisite to Basic Control Engineering.
Purpose of class
Topics cover linear system theory; mainly responses of 1st/2nd order system, stability and frequency analyses.
Goals and objectives
  1. student can solve simple differential equations applying of the Laplace transformation, and derive transfer function of the system
  2. student can obtain time response for system up to 3rd order
  3. student can determine stability of system
  4. student can obtain frequency response and Bode diagram including physical interpretations
  5. students can draw a block diagram of given system
