This paper deals with the problem of finite-time state estimation for a class of nonlinear systems possibly affected by modeling uncertainties. The proposed method, based on the high-order sliding mode control approach, is applied to develop a finite time converging state observer for a compressor system modeled by the nonlinear Moore-Greitzer system of equations. With the plenum pressure available...
In this paper we address the problem of active surge control in compressor systems by using a Close-Coupled Valve (CCV) and a Throttle Valve (TV) as actuator devices simultaneously acting on the compressor. With reference to the Moore-Greitzer compressor model, we suggest the use of a second-order sliding-mode (2-SM) technique. We show that the proposed control system can stabilize any desired operating...
