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. |
