Course Description

This course provides basic design techniques of linear multivariable feedback control systems. Modern, systematic and robust design methodologies are presented. Various applications of these robust design techniques are encountered to engineering systems such as air and space vehicles, automobiles, etc. in a set of computer aided design (CAD) homeworks. These CAD homeworks involve the usage of MATLAB software. The topics to be covered include:

  • Unstructured and Structured Uncertainty in Models of Systems
  • Performance and Robust Performance in Feedback Systems
  • Limitations of Feedback
  • LQ and LQG/LTR Design Methodology
  • H∞ Design Methodology
  • µ-Synthesis
