ROBUST LOAD - FREQUENCY CONTROLLER DESIGN

Vojtech Veselý - Ladislav Harsányi - Ivan Sekaj

   Two new approaches to the robust control design are presented. First, a design of robust discrete-time controller based on the stability robustness measures maximization is proposed. The method is simple and guarantees asymptotic stability for all admissible uncertainties. Second, a robust state adaptive continuous-time controller with partially known uncertainties is described. A new class of adaptive algorithms is proposed to guarantee the stability of uncertain linearized systems with a model without matching conditions. All methods are verified on an example of a power system load frequency control.
