Abstract: The design of variable fractional delay (VFD) finite-impulse response (FIR) filters with group delay error constraints in the least squares (LS) sense is ...

Abstract: This paper focuses on developing a fault compensation observer for actuators in a specific category of positive switched systems with time delays. The methodology involves introducing slack ...
