Control and Instrumentation

Learning Outcomes

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

• The mathematical modelling of dynamic, particularly electro-mechanical, systems.
• The principles of instrumentation and measurement systems, which demonstrates the ability to apply and integrate knowledge and understanding of other engineering disciplines to support the study of their own engineering discipline
• The fundamentals of classical control design methods, to identify, classify and analyse the performance of systems and components through the use of analytical and computer based techniques

Subject Specific Intellectual and Research Skills

Having successfully completed this module you will be able to:

• Transform continuous-time dynamics into discrete-time dynamics for control and instrumentation purposes, and perform discrete-time control analysis/design based on their analogy to continuous-time methods.
• Perform controller designs using lead-lag compensators and state-feedback.
• Understand and analyse the behaviour of nonlinear systems using the phase-plane method and describing functions.
• Analyse the stability of a system in the time and frequency domains.

Subject Specific Practical Skills

Having successfully completed this module you will be able to:

• Design an instrumentation system to include the integration of sensors, signal conditioning, and digitisation
• Construct suitable numerical mathematical models applicable to the design of control systems.
• Advance your skills in MATLAB/SIMULINK in modelling and control design
• Design control algorithms for application on real example systems

Transferable and Generic Skills

Having successfully completed this module you will be able to:

• Judge the merits of using approximate state-space, frequency response and phase plane models to solve control problems
• Gain skills in applying various control analysis and design tools into real applications through taught control examples and in the coursework.

Formative

This is how we’ll give you feedback as you are learning. It is not a formal test or exam.

Laboratory Exercises

• Assessment Type: Formative
• Feedback: Will use eAssignments to mark and provide feedback on the work
• Final Assessment: No
• Group Work: No

Summative

This is how we’ll formally assess what you have learned in this module.

Referral

This is how we’ll assess you if you don’t meet the criteria to pass this module.

Repeat

An internal repeat is where you take all of your modules again, including any you passed. An external repeat is where you only re-take the modules you failed.
