Abstract :
Nowadays, many devices are equipped with computer network interfaces. Some systems of area such as security of finance and real-time communication, synchronizing distributed clocks, rapidly, to enable their operations is imperatively required. The implementation of distributed embedded architecture which is based on IEEE 1588 standard to achieve a precise time synchronizing system is investigated. The switching controller which is combined with fuzzy and PI control schemes is proposed to reduce the time offsets from the master clock to slave clocks. The long transient time is improved with minute level via the fuzzy control. The small magnitudes of steady-state errors are reserved, completely, via the PI control.
