Abstract
In real life, everything is in movement so there are always continuous transfers,
transmissions and transports of people, materials, information and energy
to other places. These transfers, transmissions and transports occur with a time
delay. In control theory, time delays are encountered very commonly as in real
life. By considering this fact, four unstable plants with time delays are considered
from different application perspectives and five delay values are chosen. For stabilization
of these infinite dimensional plants, PD controllers are designed by three
different design methods: two of them give different least fragile PD controllers
and the other design method gives a gain margin optimizing PD controller. Designed
PD controllers and equivalent plants are put in feedback loop and robust
performance test results and step responses are obtained and compared.
