Domain.

  • Frequency domain for linear systems: root locus, Nyquist and Bode criteria,…

  • Time domain: optimal control, robust optimal control,…

Full-state, partial-state feedback.

  • Full-state feedback: the complete state of the system can be observed and used for the feedback

  • Partial-state feedback

Observers, e.g. Kalman filter, tries to estimate the state of a system from its output. Later, this estimatio can be used for feedback.
