2005/6

Aims:
The module aims to discuss further relevant control theory, modelling and design, and electronics and introduce some aspects of instrumentation.

Assessable learning outcomes:
By the end of the module the students will be able to analyse, model and design simple control systems and electronic systems and describe the operation of basic transducers.

Additional outcomes:
EA1 topics: Sensors and Transducers; Electronic Devices and Circuits
EA2 topics: Control Systems Design and Analysis

Outline content:
Modelling: review of Laplace analysis of systems; use of computer simulations to analyse systems: finding response of first and second order systems and comparisons with theoretical responses. Block diagram manipulation. Use of MATLAB in simulation and analysis.

Control: Review of systems and their response to various inputs. Characterisation of the response of second order systems. Stability of systems. Design methods for control. Frequency domain analysis and design methods using Bode. Stability. Design and analysis of discrete time systems.

Electronics: Analog op-amp circuits. V-I and I-V convertors (photo-diode amplifier). Level shifters, voltage and current references. Full- and half-wave active rectifiers (AC-DC convertors), sample and hold and PSDs, analog multiplexers. Active filters. Schmitt triggers, multivibrators and Wein-bridge oscillators. Digital Circuits. Requirements of logic circuit elements. Logic families; TTL, CMOS and ECL. Interfacing to logic families.

Measurement: Sensors and transducers, classifications, parameters. Transducers, bridges, operational amplifiers and configurations. Displacement, velocity, force, temperature and radiation tranducers.

Approximately 20% of the module is spent on modelling, 40% on Control theory, and 20% each on electronics and measurement.
