Özgür DORUK N/A The aim of this course is to teach closed loop system analysis in order to upskill the students in continuous time control system design. The students who succeeded in this course; Explain the feedback concept and its role in control system designs Derive the mathematical models of physical systems such as mechanical, thermal and electrical systems. Explain the transfer function concept and analyze the block diagrams used in control systems design. Reduce the block diagram models through block diagram algebra. Analyze the transient and steady state responses of a linear system. Make use of the expected properties of these responses in control systems design. Analyse the stability properties of a linear system. Able to apply the Routh-Hurwitz method in those analyses. Analyse the stability of closed loop system through root locus plots Analyze the stability of closed loop system through frequency response (Bode) plots. Explain the gain and phase margin concepts and make use of these definitions in stability analysis. Make use of the Nyquist plots in closed loop stability analysis. Design a simple control system by root locus method Design a simple control system by frequency response methods. Able to design a PID controller using the theory learn in class. Laplace transform, transfer functions, stability, steady-state error analysis, root-locus technique, frequency response technique.
