TLDR
The article shows that given a specific process and open-loop modulus and phase specifications, the gain crossover frequency must be selected such that the process phase fulfills an important condition (design constraint) and the proposed approach ensures that the tuning parameters of the fractional order controller will have a physical meaning.Abstract:
Fractional order proportional integral and proportional derivative controllers are nowadays quite often used in research studies regarding the control of various types of processes, with several pa...read more
