An introduction to process dynamics and process control technology.
The course will be taught both via a real-time approach involving the hands on use of dynamic simulation and building on classical process dynamics knowledge developed in earlier years. (The course does not use the classical Laplace Transform approach).Topics• Dynamic process modelling • Process dynamic elements such as resistive, capacitive, first-order, oscillatory and dead-time elements• Behaviour of systems of dynamic elements using MATLAB and Excel• Control hardware including controllers, sensors and valves• Basic feedback control concepts and the Proportional-Integral-Derivative controller• Closed loop stability and empirical tuning of controllers• Cascade, ratio and feed-forward control• Control of unit operations
Learning OutcomesTo ensure that all students and graduates fully understand the need to name, date and clearly document all files, spreadsheets and computer programs.To understand the dynamics elements that affect the dynamics of a process such as first-order response, dead time, and capacity.To be able to simulate using Excel and Matlab, the dynamics response of systems made up of typical dynamic elements.To become familiar with some typical items of control hardware that are used in industry.To understand PID control well enough to be able to simulate and tune a real process.To be able to simulate more complex control including cascade, ratio and feed forward.To know which control loops might be suitable for a range of unit operations.

COMPUTER EXAMThe computer exam might require you to use Excel, Word and Matlab in an examination environment. You will need to know how to use these, how to save files, and how to upload these files into Learn. Inability in more than one of these may lead to failure.Some of the assignments will be done in pairs. You may not choose to work with the same person twice (with the exception of the process dynamics lab which can be done with the same person as assignment 1).LABORATORIESProcess dynamics Lab, held in weeks 5-6 (15-24 August 2017). You will carry out experiments to determine the dynamics of a tank with continuous flow and a heat pulse input. First you will set up a simulation in Matlab and then refine the simulation to match the process.Controller tuning lab, held in weeks 8-10 (19 Sept – 6 Oct). In this short lab you get to change test controller tuning on the heated tank.
