Abstract

A nonlinear controller design method is proposed for active surge control of compression system. Close-coupled valve (CCV) is used to modify the characteristic of the compressor, and allows for stable operation beyond the original surge line. The controller is constructed on the uncertainty and disturbance estimator (UDE) approach. The algorithm provides excellent stabilization and disturbance rejection performance. Simulations are given to show the effectiveness of the method.
