Linear Dynamical Systems

  • Kurskod: FSSY055
  • ECTS-poäng: 7,5
  • Institution: ELEKTROTEKNIK
  • Forskarskola: Signaler och system
  • Periodicitet: Every second year, next time it will be given in spring 2018
  • Undervisningsspråk: Kursen kommer att ges på engelska
Aims
Learning the state space and frequency response methods of analysing linear systems. Learn- ing basic ideas needed for further study of nonlinear control, adaptive control, and multivariable control design methods such as H∞ synthesis.

Content
  • Time domain Analysis: Linear differential equations with (i) constant coefficients, (ii) time-varying especially periodically varying coefficients. Controllability, Observability, State feedback and output feedback. Realizations from weighting patterns, and minimal realizations.
  • Least squares theory: Minimization in inner product spaces, Spectral factorization.
  • Frequency response techniques: Smith-McMillan form, Multivariable poles and zeroes. Matrix fraction description and Youla Parametrization. Introduction to multivariable control synthesis.
  • Stability: Lyapunov equation, Circle criterion, Kalman-Yakubovich-Popov lemma, Multi- variable Nyquist criterion and Gershgorin bands. Stability of time-varying, and periodically varying systems.
Method of evaluation
Pass/Fail grade. To get a Pass grade, the student must submit attempts to all six assignments, and must also pass the final take-home exam. The final exam will be handed out on the last day of class, and the written answers will be due two weeks from then.
