The aim of this subject is to introduce the key concepts of control systems to the student.The importance of the incorporation of feedback in automated systems is emphasised. The student is introduced to the notation and methodology used for evaluating control systemperformance. DC motor control systems are used as examples and aspects of digital control are introduced using PLC and digital sensors.
MODELLING and TRANSFER FUNCTION:
Principles of system modelling; Understanding transfer function in time domainand S domain; Stability analysis; Dynamic behaviour of 1st and 2nd ordersystems; System steady state and transient state analysis based on transferfunctions.
FEEDBACK CONTROL:
Block diagram representation; Benefits of negative feedback control; Steadystate error analysis; Analysis of transient response; Analysis of controlperformance; On/Off control; Simple Proportional Control; Proportional,integral and derivative Control; Feedback control of systems with time delay. DC Motor Control.
DC Motor Control:
Principles of DC Motor Control, Modelling of DC motor, PID control design of DC Motor, stability and control performance analysis.
Sensors and Transducers:
Fundamental classification of sensors and transducers; Interface standards for analog and digital signals; A selection of discrete sensors, such as limit switches, proximity sensors, photoelectric sensors etc.
PROGRAMMABLE LOGIC CONTROL:
PLC hardware; Binary number systems; Digitallogic gate circuits, Basic PLC programming techniques and introduction of somecommonly used components, such as relays, contactors, overloads, emergencystops, switches and sensors.
