Abstract-- In this paper, a neural networks (NN) based adaptive sliding mode controller (SMC) is introduced. The
selection of SMC feedback gains is normally based on one operating point and thus the performance of the
controller away from the design operating point is, of necessity, a compromise. The Adaptive SMC is proposed to
overcome the limitations imposed on the effectiveness of the SMC under different operating conditions. Neural
networks are used for on-line prediction of the optimal SMC gains when the operating point changes. The
proposed method has been applied to a power system stabilizer (PSS) of a single machine power system.
Simulation results are included to demonstrate the performance of the proposed control scheme.
Key Words: Neural networks, sliding mode control, power system stabilizers, Genetic algorithms.
