Control and Instrument Systems
This module introduces the learner to the key principles and performance parameters of scientific and industrial instruments, and provides expertise in the application of such principles. It also provides an introduction to the principles and practice of control systems and automation.
Use and optimise a range of basic electronic test and measurement equipment including meters, oscilloscopes, function generators and timer counters.
Interpret instrument specifations correctly, verify that instruments are operated safely and within specifications, and calibrate basic measurement equipment.
Explain the mode of operation of key sensors and transducers and implement appropriate calibration and signal conditioning.
Measure, record and analyse data with a range of sensors and transducers.
Choose the optimum sensor and /or instruments for specific applications and make sensible decisions on the purchase of suitable scientific equipment to meet requirements.
Explain the differences in performance between open- and closed-loop control systems and explain the principles involved in such systems.
Describe the function of a process controller and the use of proportional, derivative and integral control laws. Explain PID control and how such a controller can be tuned.
Describe the forms of commonly used pneumatic / hydraulic and electric correction elements.
Define the term transfer function and explain how it is used to relate outputs to inputs for systems. Use simple building blocks to model systems and use block diagram simplification techniques to aid in the evaluation of the overall transfer function for the system.
Model dynamic systems by means of differential equations. Characterise the response of first-order systems to inputs.
