EE 4720 - Control Systems Applications

2 lecture hours 2 lab hours 3 credits

Course Description
This course extends the classical continuous time control techniques to the areas of discrete-time systems and state-space models. An independent hardware project is required that demonstrates the principles of control system analysis, modeling, and design. Control systems are analyzed, modeled, and designed using frequency response, z-transform and state-space techniques. (prereq: EE 3220 or EE 3221, EE 3720)

Course Learning Outcomes
Upon successful completion of this course, the student will be able to:

Determine the open-loop and closed-loop transfer functions of a system containing a sampler and zero-order-hold
Determine the stability of sampled data (discrete-time, DT) systems
Design DT system compensators
Analyze system controllability and observability
Design state feedback estimator-regulators
Build a control system from the component level that includes actuation, transducer feedback, and closed-loop compensation
