## CONTROL ENGINEERING 3

 SHE Level 3 SCQF Credit Points 20.00 ECTS Credit Points 10.00 Module Code M3H606414 Module Leader George Cullen School School of Computing, Engineering and Built Environment Subject Instrumentation and Control Trimester A (September start)

### Pre-Requisite Knowledge

Control and Instrumentation Systems and Mathematics 2A & 2B or Maths for Engineering 3 (HND) or new Engineering Mathematics 5

### Summary of Content

The aim of this module is to provide the student with a foundation in control system design.

### Syllabus

The teaching syllabus will cover the following areas: Analysis of systems using Laplace - the Laplace transform and its application to the solution of differential equations. Mathematical modelling of system components. Transfer functions of basic system components such as electric motors, valves, linkages, etc. Block diagram representation of open and closed-loop control systems. Block diagram reduction of open and closed-loop control systems. Time domain analysis- step response characteristics of first and second order systems. Frequency domain analysis- Nyquist ( polar ) diagrams, Bode plots. Measuring gain and phase margins from Nyquist and Bode plots and estimating system stability. Effect of gain on stability. Methods of improving control system performance such as compensators, PID controllers, including the practical electronic circuits or programs to achieve compensation. The syllabus consists of a list of topics normally covered within the module. Each topic may not be dealt with in the same detail.

### Learning Outcomes

"On successful completion of this module students should be able to:"1. Distinguish between on/off, open-loop and closed-loop control systems and identify suitable applications for these control systems.2. Derive transfer functions for basic electrical and mechanical system components (mathematical modelling).3. Calculate using block diagram reduction techniques the transfer function of open and closed-loop continuous control systems.4. Calculate and sketch the response of first-and second order systems in the time and frequency domain.5. Plot poles and zeros on the S-plane and use dominant pole simplification techniques to predict the dynamic response of 3rd, 4th, 5th and higher order systems.6. Calulate gain and phase margins using Nyquist and Bode plots and estimate the stability of closed-loop control systems. 7. To improve control system performance using compensators and PID controllers.
