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.
On the successful completion of the course, students will be able to:
Describe dynamical systems in mathematical terms using state-space representations.
Analyse dynamical system properties of state-space models.
Develop feedback controllers for state-space models using state-feedback and observer techniques.
Design PID type decoupling controllers for the MIMO systems with transfer function representation
Design IMC type controllers for both minimum phase and non-minimum phase MIMO systems
Evaluate the MIMO control system performance in terms of reference tracking, noise suppression and disturbance rejection.
