Objectives At the completion of this subject students will understand the principles of feedback control, have the skills to analyse a given linear control system, and know the pole positions desirable for some applications. Students will appreciate that linear operational-amplifier circuits exemplify the principles of feedback control. Students will understand the basic operation of semiconductor diodes and transistors, know how to analyse linear circuits which incorporate these nonlinear devices, and understand how nonlinear devices can in certain circumstances be given a linear representation.

Synopsis Control: dynamic response of linear systems. Reasons for feedback control. Poles and zeros. Stability of feedback systems. Routh array. Steady-state error and system type. Control design using root-locus. Electronics: semiconductor diodes: V-I characteristic. Diode applications: piecewise-linear equivalent circuits, rectifier, voltage multiplier. V-I characteristics of BJT and FETs. 3-terminal devices in circuits: load line and transfer characteristic. Nonlinear circuits: clippers, clampers, logic gates. Amplifiers: quiescent point and small changes, simple biasing, small-signal equivalent circuits, linear circuit analysis. Ideal operational amplifiers: linear applications of feedback. Elementary dynamics of operational-amplifier circuits.
