Digital Control System Design

Digital Control System Design (ENG321)


This course provides students with the analytical tools to understand systems from digital control engineering perspective and the tools and technologies to solve such problems. It guides students to identify relevant system properties and parameters and to formulate mathematical models that allow the use of either classical or modern control theories to evaluate system performances and to design feedback control solutions to meet performance specifications. It can be applied to sensors and transducer systems, to modeling and understanding of biomedical systems as well as in the manufacturing of batch products (pharmaceutical and drugs), discrete components and systems (disk drives, automation and MEM) and flow processes (petrol-chemical and oil and gas). Students will also be introduced to Computer simulation Design Tools such as Matlab/Quanser.
