EE2010 Systems and Control (Chapter 1) 1-4 Topics to be Covered(1) Models of physical systems in various forms, e.g., time domain models, frequency domain models Circuit models as examples of physical systems Transfer function models, G ( s ), are given to linear time invariant systems Propagation of signals through a system, e.g., impulse response, step response, sinusoidal response Frequency response of G ( j ) models, e.g., Bode plots
EE2010 Systems and Control (Chapter 1) 1-5 Feedback systems and their benefits Open loop control; Feedback systems as closed loop control systems Positive and negative feedback; Advantages of closed loop vs open loop control Stability Notions of stability - When does a system become unstable? How do you analyze or assess stability? Use of root locus plots in stability analysis; Nyquist stability criterion Topics to be Covered(2)

EE2010 Systems and Control (Chapter 1) 1-6 Performance of feedback systems What characterizes performance – transient and steady state responses Steady state and transient responses Pole placement designs: PID control Gain and phase margins Design of simple control systems Topics to be Covered(3)
EE2010 Systems and Control (Chapter 1) 1-7 As engineers and scientists, what are we interested in? Understanding the physical world around us in order to Improve human-environment interaction Design and fabricate entirely new devices What tools are needed to achieve the two objectives? Verbal description is limited as it is imprecise Mathematics is more powerful One of the important roles for scientists and engineers is to describe and analyze behavior of physical world using mathematical tools Signals and Systems
