Summary of Content

A firm foundation is provided in the general theory of control systems and instrumentation. Problems with a substantial mechanical and electrical component are tackled in an integrated approach. Emphasis is directed mainly towards application of significance to building services engineering. There is a substantial practical content to this module.


The taught syllabus will cover the following areas: CONTROL Basic Control Concepts: Basic definitions of process, sequential and protection control systems, open and closed loop systems; continuous and discontinuous control; evaluation criteria for stability, regulation and transient conditions; gain and feedback, response to step, ramp and sine wave inputs. Controllers: Final control operation; signal conversion, electrical, mechanical, pneumatic, hydraulic actuators; mechanical, electrical and fluid control elements; objectives of analog and digital controllers. Discrete Control Systems: Definitions of discrete-state process control; characteristics of such systems; mechanical/electrical interface devices, electromagnetic relays; ladder diagrams and its elements, programmable logic controllers; introduction to the microprocessor; discontinuous controller modes. Continuous Control Systems: Control system parameters for system evaluation; continuous system operating in proportional, integral, derivative and composite modes. Control system configurations; single and multivariable systems, quality, stability & system response, process loop analysis using basic response methods. INSTRUMENTATION: The Measurement Process: Description of the process, references, scaling, counting, calibration, direct and null measurement, null detectors, feedback. Examples: time and frequency, analogue to digital conversion. Use of computers for calibration, compensation and automatic null measurement. Signal sources for measurement - transducers. Transducers and Actuators: Classification of transducers; energy converting, parametric, quantum detectors, digitising. Primary sensing elements. Transducers and actuators as system elements; static and dynamic performance; transfer functions; signal conditioning. Analog Signal Conditioning: Principles of analog signal conditioning; passive circuit elements; characteristics and application of operational amplifiers, introduction to basic electronic devices. Digital Signal Conditioning: Principles of digital signal conditioning; binary, hex, numbering systems; Boolean algebra; Karnaugh mapping; basic digital devices, converters, multiplexers; data acquisition systems.
