Decentralized robust flow controller design for networks with multiple bottlenecks
Munyas, I.; Yelbasi, Ö.; İftar, Altuğ (Institute of Electrical and Electronics Engineers Inc., 2003)Decentralized rate-based flow controller design in multi-bottleneck networks is considered. An H? problem is formulated to find decentralized controllers which are robust to time-varying uncertain multiple time-delays in ... -
Fault diagnosis on hermetic compressors based on sound measurements
Toprak, Suha; İftar, Altuğ (IEEE, 2007)A fault identification study is made to identify five common faults in hermetic compressors manufactured in a large plant. Sound power level is used as raw data. Sound measurements were made in a room where microphones ... -
H-based flow control for ATM networks with multiple bottlenecks

Inclusion principle and overlapping decompositions of distributed-time-delay systems
İftar, Altuğ (IFAC Secretariat, 2014)The inclusion principle for distributed-time-delay systems is defined. The properties of input-output map equivalence and preservation of stability between two systems, one of which includes the other, are presented. ... -
An inclusion principle for discrete-event and hybrid systems
İftar, Altuğ (IEEE, 1997)Hybrid systems, which consist of continuous-state and discrete-state parts are considered. It is assumed that the discrete-state part of the system is event-driven. Inclusion and extension principles are first defined for ... -
Inclusion, Restriction, and Overlapping Decompositions of Neutral Systems With Distributed Time-Delay
