Abstract This paper presents a design of a sliding mode controller (SMC) with
chattering reduction feature applied to interconnected Automatic GenerationControl
(AGC) model. The proposed method formulates the design of SMC as an optimization
problem and utilizes Particle Swarm Optimization (PSO) algorithm to find the optimal
feedback gains and switching vector values of the controller. Two performance functions
were used in the optimization process to demonstrate the systemdynamical performance
and SMC chattering reduction. The tested two-area interconnected AGC model
incorporates nonlinearities in terms of Generation Rate Constraint (GRC). Comparison
with a previous AGC method reported in literature validates the significance of the
