Undergraduate 3 0 3 5
Obligation : Must
Prerequisite courses : ELE301
Concurrent courses : ELE356
Delivery modes : Face-to-Face
Learning and teaching strategies : Lecture, Question and Answer, Problem Solving, Other: This course must be taken together with ELE356 CONTROL SYSTEMS LABORATORY.
Course objective : The main purpose of this course is to teach fundamental analysis methods for control systems. The analysis methods discussed in the course are also useful for control system design; however analysis aspects of the methods will be emphasized. Various methods for transient analysis, steady-state analysis and stability analysis will be studied. To that end, after a comprehensive introduction to systems modeling; both frequency domain and time domain approaches are studied in detail. Design point of view is given implicitly via analysis examples. The topics covered in the course are reinforced via experiments conducted in ELE 356 (Control Systems Laboratory).
Learning outcomes : A student who completes the course successfully will 1. Understand the basic principles and characteristics of feedback control systems. 2. Obtain mathematical models of various physical systems. 3. Perform stability analysis of feedback control systems via different methods. 4. Understand the design and realization of control system components to meet given specifications. 5. Recognize, formulate and solve some control engineering problems. 6. Have a working knowledge of existing software tools necessary both for control engineering practice and academic research.
Course content : Historical perspective of control systems. Basic concepts of open-loop and closed-loop, feedback. Models of physical systems: electrical systems, mechanical systems, fluid systems, thermal systems, servomotors, electro-mechanical systems. Block diagrams, signal-flow graphs. Time response analysis, steady-state error analysis. Sensitivity, disturbance rejection and stability analysis, Routh-Hurwitz criterion. Root-Locus plotting. Frequency response analysis: Bode, polar and magnitude-phase plots, Nyquist analysis, gain/phase margins, Nichols chart. State-space analysis: State-space description, state transition matrix, similarity transformation, diagonalization of system matrix, modal decomposition, companion forms, transfer function decomposition, controllability and observability. State-space design: State feedback, state observer.
