Summary of Content

The aim of this module is to provide the student with a foundation in instrumentation and control systems technology. First an understanding of control system components, such as sensors and associated instrumentation systems, actuators, and power amplifiers, will be developed, followed by a study of their integration and use in discrete and continuous control systems.


The teaching syllabus will cover the following areas: Transducers and Associated Signals: Signal and system characteristics - deterministic and random signals, periodic and aperiodic signals, properties of signals. Examples of signals obtained from transducers and their associated signal conditioning circuits. Introduction to Instrumentation and Signal Conditioning: Use of signal conditioning circuits such as Wheatstone bridge circuits, instrumentation amplifier, analogue to digital and digital to analogue converter. Description of signal conditioning circuit operation and characteristics. Pneumatics/Hydraulics: ISO1219 Fluid Power symbols of pneumatic units and components; functions of pneumatic components; fields of application of pneumatic systems; design of pneumatic circuits; construction of pneumatic circuits; locked signals and use of cascade valves; design of cascade systems. Other actuators:Electric motors; pneumatic and hydraulic cylinders; solenoids, relay components. Programmable Logic Controllers: Block diagram representation of PLC architecture, inputs and outputs; ladder diagrams for given control situations; PLC programming from ladder diagrams; testing PLC programs; motion control/timing diagrams. Control Systems: Open and closed loop control systems; components of control systems; control system performance characteristics. Construction of control systems using microcontrollers, computers and PLC.s Controllers: On/Off controllers; proportional, integral and differential controllers; effect of controllers on system performance. The syllabus consists of a list of topics normally covered within the module. Each topic may not be dealt with in the same detail.
