| DESCRIPTION | Performance of Control Systems: - Definition of stability and link between CLTF poles and stability; - Routh Stability Criterion; - Closed-loop system performance: System types, steady state errors, error constants, time domain specifications, sensitivity functions and noise rejection; - Root-locus techniques. Frequency Domain Analysis of Stability: - Phase and Gain Margins from Bode plots; - Nyquist Stability Criterion and Nyquist Plots; - Nichols Plots. Study-unit Aims: This study-unit develops the concepts of classical automatic control theory introduced in SCE2111, concerning analysis of linear time-invariant feedback systems, with particular emphasis on stability using root-locus and frequency response techniques. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to, given the mathematical description of the linear dynamics of a system: - explain the conditions of closed loop stability in both the time and the frequency domains; - explain the system's closed loop behaviour for changing closed loop gain. 2. Skills: By the end of the study-unit the student will be able to, given the mathematical description of the linear dynamics of a system: - analyse the performance and stability of closed loop systems by mathematical methods; - obtain root loci for the system's closed loop poles for changing open-loop gain; - analyse the stability of closed loop system from frequency domain plots such as Bode, Nyquist and Nichols plots.
