Abstract :
The paper presents a new approach to the design of a robust controller for the auxiliary control loop of a static VAr system using both fuzzy logic and variable structure system (VSS) concepts. Also, the design of a simple fuzzy controller using the least number of rules for stabilisation of a synchronous generator connected to a large power system is presented. The performances of fuzzy, variable structure fuzzy and VSS stabilisers are compared with a conventional stabiliser for a variety of transient disturbances, highlighting the effectiveness of these stabilisers in providing significant damping to the system oscillations
