Resumen
The stability of synchronous generators connected to power grid has been the object
of study and research for years. The interest in this matter is justified by the fact that much
of the electricity produced worldwide is obtained with the use of synchronous generators.
In this respect, studies have been proposed using conventional and unconventional control
techniques such as fuzzy logic, neural networks, and adaptive controllers to increase the
stabilitymargin of the systemduring sudden failures and transient disturbances. Thismaster
thesis presents a robust unconventional control strategy for maintaining the stability of
power systems and regulation of output voltage of synchronous generators connected to
the grid. The proposed control strategy comprises the integration of a sliding surface with
a linear controller. This control structure is designed to prevent the power system losing
synchronism after a sudden failure and regulation of the terminal voltage of the generator
after the fault. The feasibility of the proposed control strategy was experimentally tested
in a salient pole synchronous generator of 5 kVA in a laboratory structure
