This course treats the basic principles of the automatic control of industrial processes and machines. The emphasis of the subject is on continuous time control, although some introductory material on sequential logic control (or programmable logic control) is included.
- Semester 1 - 2015
- Trimester 2 - 2015 (Singapore)
1. Formulate quantitative models of feedback control systems built from mechanical, chemical, electrical and electronic components described by linear, ordinary differential equations
2. Analyse single input, single output feedback control systems for stability, steady state and transient performance
3. Understand the scope and limitations of fundamental control strategies, and be able to design simple compensation schemes for improved control; and
4. Understand the basics of using programmable logic controllers (PLCs) in implementing switching control systems.
