RELIABILITY ANALYSIS OF FRACTIONAL - ORDER FUZZY PID CONTROLLERS
Аннотация
This paper presents a comprehensive reliability analysis of Fractional-Order Fuzzy PID (FOFPID) controllers applied to dynamic and nonlinear industrial systems. The FOFPID controller combines the advantages of fractional calculus and fuzzy logic to improve control precision, adaptability, and robustness under uncertain operating conditions. In this study, the reliability indicators of the controller—such as mean time between failures (MTBF), fault tolerance, stability margin, and sensitivity to parameter variations—are analyzed both theoretically and through simulation. The proposed reliability model is verified using MATLAB/Simulink environments for different types of dynamic plants, including first-order and higher-order nonlinear processes. The obtained results demonstrate that the FOFPID controller maintains high performance stability even under component degradation and stochastic disturbances, outperforming classical PID and FOPID structures.
