Linear Control Systems

This module includes lectures & laboratory classes on control systems modelling, analysis & design techniques. Methods include the Nyquist stability plot, the Nichols chart and the root-locus, along with an introduction to proportional, derivative, integral & PID controller design. Lab classes illustrate applications in DC motor position & speed control, simulated process control and feedback amplifier design.

Learning Outcomes
1.Use a polar plot to determine the level of stability of a closed-loop system from open-loop test/model data.
2.Use a Nichols Chart as an aid in control system design and analysis.
3.Use the Root-Locus method in the design of controllers.
4.Sketch control system step responses from closed-loop pole-zero maps.
5.Apply appropriate design strategies to meet basic performance specifications.
6.Choose appropriate controller settings to meet performance specifications.
