Nonlinear H_∞ stabilizers design for power systems

摘要

In this paper, some new results on nonlinear H_∞control for affine nonlinear systems are developed. Although the HJIinequality derived in H_∞ control is not easy to solve,for some nonlinear systems, by using some variable replacement orchoosing a suitable penalty variable, the inequality can be turned to bean algebraic inequality. A design procedure of nonlinear H_∞ excitation controllers for power systems is given
