Aims

This course unit detail provides the framework for delivery in the current academic year and may be subject to change due to any additional Covid-19 impact.  Please see Blackboard / course unit related emails for any further updates

The course unit aims to:·    

  • Give students a sound understanding of control systems analysis and synthesis using state space techniques
  • Introduce multivariable control systems
  • Give students an introduction to internal model control design.
