Exclusions
Description	Part A of the module: Introduces students to modelling, process dynamics and practical process monitoring and control. The importance of control for process operation will be explained, and the structure of modern plant-wide control systems will be described. The module will discuss typical process monitoring devices for common variables (pressure, temperature, level, flow, etc.), and show how signals are generated by these and transduced, transmitted and, if necessary, transformed for use in the control system. The fundamentals of open- and closed-loop control will be discussed and controller actions outlined. A review of process modelling and its basic procedures will be used to explain the concept of dynamic behaviour of processes. Methodologies for solving the differential equations resulting from unsteady-state balances over selected process examples will be given, in particular for linear, second-order differential equations. Practical examples will also be given of processes and instruments demonstrating common types of dynamic behaviour. Part B of the module: This builds upon and covers the basic principles of analysis and design of process level control systems, and the appropriate mathematical tools. Topics discussed include transfer functions, ideal dynamic systems, classical PID controllers, feedback control block diagram analysis, stability concept and analysis, structure and components of modern control loops, and practical aspects of industrial process control
Learning Outcomes	By the end of the module students should be able to: appreciate the importance of process control and the role of the process control engineer particularly in safety critical systems; comprehend the basic structure of control systems and how open- and closed-loop control is carried out and how the analysis and solution of dynamic models (particular linear 2nd order differential equations) is required; describe primary sensing elements used for commonly measured and manipulated process variables select the appropriate final control element for a given process application and how these are used within control loops on process plant; understand elementary control concepts, defining feedback and feed-forward modes of control and use relevant software and analytic tools (including Laplace Transforms and Simulink) to analyse;
