Learning Outcomes

Thinking, concepts, analysis and synthesis needed to control deterministic systems of various complexity, especially for LTI (Linear Time Invariant) systems in DT (Discrete-Time) but also for CT (Continuous-Time). The student should (for grade 3/5): 1. Recognize the basic concepts and elements of systems control needed and relate the methods studied to them. 2. Master identification of ARX models and model conversions (between CT and DT models, between state-space models and transfer function models.) 3. Know the similarities and differences in the CT and DT time domain and frequency domain theory of systems (due to elementary knowledge from a course of CT control) 4. Master Root-Locus Theory exluding angle rules. 5. Perform analysis of stability, controllability (reachability) and observability of a DT LTI state-space model. 6. Design and analyze LTI State-Feedback Controllers and LTI State Observers for LTI DT state-space plants 7. Recognize and handle obvious risks of poor control or computations. Grade (1/5): At least four of the goals listed are reached
