4 points * 26 lecture hours, 26 laboratory hours * First semester * Caulfield * Prerequisites: ELE3232
Objectives Process system control, the relationship between continuous time systems and discrete time systems, and the structure of computer controllers used in commercial applications.
Synopsis Process concepts: basic process elements, plant, measurements, controller. Control loop topologies. Control hierarchies: direct digital control, supervisory control, distributed control configurations, batch sequencing, process interface. Modeling and identification: development of first and second-order models. Sampled data theory: z plane, stability, transforms, closed loop sampled systems. DDC algorithms and tuning, digital filters - deadbeat, Dahlin PID controllers. Selection of sampling interval. Multiloop control schemes, feedforward, cascade, interacting loops and decoupling.
Assessment Examination (3 hours): 60% * Laboratory work: 40%
