摘要
Based on the improve dynamic surface control (IDSC) method and disturbance attenuation technique, the nonlinear adaptive robust controllers of power systems coordinated control for SVC and generator excitation are proposed in this paper. The IDSC method is combined with the sliding mode control, and the parameter adaptive laws are not based on the certainty equivalence criterion. Because during controller design procedure besides the external disturbances are considered, some parametric uncertainties are considered as well. Thus the derived controller can guarantee the whole errors system globally and uniformly ultimately bounded. Theory analysis and simulation results show that the proposed coordinated controllers have the effectiveness and accuracy in a single machine to infinite bus (SMIB) system. 1553-9105/Copyright © 2014 Binary Information Press
