Module Details

Learning Outcomes

Have a good understanding of how to calculate and analyze dynamic behavior of physical systems, including fundamental notions of dynamics like stability and transfer function.

Use and simplify block diagrams

Construct and interpret Bode diagrams and root locus diagrams

Understand the significance of controller actions (proportional, integral, derivative).

Apply methods of optimal tuning of PID controllers

Prerequisites

There are no prerequisite modules. Students should have some basic knowledge of differential equations and mass and energy balances
