Research on Terminal Piecewise Sliding Mode for Excitation Control System Based on the Nonlinear Disturbance Observer

Abstract:

Aiming at uncertainty and disturbance of the excitation system, we designed a kind of precise sliding mode controller with nonlinear disturbance observer that realized disturbance estimation and compensation. In order to obtain better convergence rates, based on the basis of fast terminal sliding mode surface, terminal piecewise sliding mode is adopted. Using the single machine infinite system, we have carried on the static and transient simulation. Simulation results show that control strategy adopted can guarantee system robustness to disturbance and has high control precision
