Abstract
This paper describes a new approach to control stall and surge instabilities in the compressor
system by using of finite time backstepping-based adaptive sliding mode method. The most
important innovation of this study is to provide a finite time adaptive control method to simultaneously prevent the stall and surge instabilities in a compressor system in the presence of
disturbance and uncertainty in the compressor characteristic curve as well as the throttle valve.
The disturbance and uncertainty issues are covered by a robust sliding mode control and the
gain coefficients of this controller as well as the estimation of uncertain terms are obtained by
using the adaptive method. The Lyapunov stability criterion is used to evaluate the finite-time
stability of the closed-loop system. The performance of the proposed method is compared with
other literature methods through simulation in Matlab. The simulation results show that the proposed controller is better than the existing methods in terms of surge preventing and robustness
against uncertainty and disturbance.
