Robust adaptive control of chaoic power systems with uncertainty

For the tracking control problem of chaotic power systems containing constant parameter uncertainties and external disturbances, an adaptive robust controller is designed based on the dynamic surface control method. The proposed adaptive robust control guarantees the closed-loop to be semi-globally asymptoticaUy stable, and makes the output track the desired trajectory. The theoretical analysis and simulation results show that the derived adaptive nonlinear tracking controller can suppress the chaotic oscillation of simple power systems effectively, and owns certain robustness and adaptability.
