Pre-requisite learning
Module Recommendations

This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).

Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
No incompatible modules listed
Co-requisite Modules
No Co-requisite modules listed

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.

Module Content & Assessment

Indicative Content
Introduction to Control
The need for control, block diagrams, open and closed loop control, positive and negative feedback, analog control versus discrete control. Basic control equations and control definitions
Control Modes
Principle and function of the controller, discontinuous and continuous modes. Proportional, integral and derivative (PID)concepts. Composite control modes, examples and applications.
Control Strategy
Simple control strategies applicable to the process industries. Time-domain analysis of process output. Zeigler-Nichols tuning methods.
Control Valves
The valve as final actuation element, current to pneumatic converters, direct and reverse acting. Valve trim including plugs, seats and positioners. Calculations on valve sizing.
Practical Programme
Two position control using thermistor, valve characterisation, PID modelling of flow and temperature, PID control of a cascade control rig, orifice plate flow system and tank level process. Zeigler-Nichols tuning technique
