CONTROL OF UNCERTAIN SYSTEMS

Mária Dúbravská - Ladislav Haršányi

   The paper deals with the frequency domain robust PID controller design for linear continuous-time systems. The uncertain system is given by a finite number of transfer functions. The design method evolves from the frequency domain robust stability criteria for unstructured uncertainty, and from the Small Gain Theorem based stability condition. The proposed design algorithm is illustrated on an example.

Keywords: structured and unstructured uncertainty, additive uncertainty, robust stability
