Finite-time active fuzzy sliding mode approach for deep surge control in nonlinear disturbed compressor system with uncertainty in charactrisitic curve

In this paper, a novel active control approach is designed for surge instability in the compressor system using finite-time fuzzy sliding mode scheme. The primary novelty of study lies development presence disturbance and uncertainty characteristic curve also throttle valve. To ensure stability closed-loop Lyapunov's concept, finite time method proposed based on estimation robust adaptive methods. Achieving rapid elimination deep occurs through fast design, while techniques are used to estimate nonlinear terms, as well obtain optimal weights. simulation results MATLAB environment comparison show that suggested provides better quality terms suppression, robustness, overcoming effects.
