Teaching Method

Outline:

In Control Engineering 2, the stability of the feedback control system and its discrimination method are learned based on the basic knowledge from the transfer function expression of the system learned in Control Engineering 1 to the frequency response characteristics of the control system. Furthermore, the purpose is to understand the evaluation method using deviation constants for steady-state characteristics, and to understand the analysis methods related to series compensation circuit design such as gain adjustment and phase adjustment.

Style:

It is assumed that you have basic knowledge of the feedback control system, such as the transfer function and block diagram learned in Control 1 and in Control Engineering 2, you can check the control performance of the control system and the design using the compensation circuit through exercises. I want you to acquire the ability to understand and apply the contents of control theory instead of just memorizing the solution of problems.

Notice:

A quiz may be given at the end of the lecture to aid understanding. In addition, it will be necessary to submit a task report such as end-of-chapter problems to confirm understanding.
