Objectives The student is expected to gain knowledge and understanding of system hardware, mathematical modelling in time, frequency, Laplace and state domains and application of feedback and compensation design to modify performance relative to specifications.
Synopsis The nature of automatic feedback control. Open loop and closed loop systems. Block diagram representation. Definitions and terminology. Basic closed loop transfer function. Effect of feedback on gain, distortion, and sensitivity to parameter change. Derivation of system equations. PID controllers and tuning. S-plane theory, differential equation solution by poles, zeros. Signal flow graph and reduction by Mason's Rule. Error analysis. Frequency response. Transfer function from the frequency response. Nichol's chart closed loop frequency response. Stability criterion. Gain and phase margins. Nyquist diagram, simple and full stability test. Root locus plotting. Closed loop performance from the root locus. State variable representation, transfer matrix, closed loop analysis. Feedback system compensation analysis and design, by root locus and frequency response techniques. Lag-lead networks.
