On Boundedness of Solutions of Three-State Moore–Greitzer Compressor Model with Nonlinear Proportional–Integral Controller for the Surge Subsystem
(2026) In Systems & Control Letters 216.- Abstract
- The work focuses on Lagrange stability of the origin for the three-state Moore–Greitzer compressor model in closed loop with a nonlinear PI controller, tuned only to stabilize a lower-dimensional invariant surge dynamics subsystem. The linearization of the system is not stabilizable but the static nonlinearity satisfies a sector condition, and together with a structural property of the stall-dynamics subsystem, this plays an essential role in the analysis. The main contribution provides explicit conditions on the controller parameters together with analytical arguments that guarantee boundedness of all solutions of the closed-loop system. The analysis employs a non-standard application of Circle-Criterion-based arguments. Together with the... (More)
