Chaos control of an extended four dimensional fundamental power system using sliding mode control

In this paper, control of chaos in an extended four-dimensional fundamental power system (FDFPS) using sliding mode control (SMC) is considered. First order sliding mode control laws are derived in order to control the chaotic behaviour in FDFPS. The sufficient stability condition is devised for the designed sliding manifold based on Lyapunov stability theory. The proposed control law simplifies the controller design of power system stabilizer and provides an effective and robust control to avoid the instability in the FDFPS. Simulation is presented in MATLAB environment and reveals the effectiveness of proposed SMC scheme.
