Abstract

We aim to design a fractional order robust control system. It is an advanced model of classic PID controller whose order will be non-integer.PID controller that we generally use has many advantages and disadvantages with respect to the disadvantages like, it doesn’t give accurate values of constants, exact values of the time domain parameters as well as frequency domain parameters of the control system and we have more robust problem. Wearable electronic based an automatic voltage regulator can automatically preservesthe terminal voltage of generator at a fixed value under varyingly load and operating temperature. AVR controls output by sensing the output voltage at a power-generating coil and compares it to a stable reference. The combination of fractional order controller with an automatic voltage regulator is proved to be better than conventional controllers.

Highlights

  • Oustaloup is the pioneer in the field of fractional order calculus

  • It is employed in contrastive feedback control systems

  • In general for any control system gain margin and phase margin are the signs of strength

Summary

Introduction

Oustaloup is the pioneer in the field of fractional order calculus It was known as command robusted order non-entier (CRONE) controller. In the recent times podlundy a scientist introduced a generalized fractional PID controller called the fractional order PID controller that offers many advantages and advanced than the classic PID controller that includes (integrative action) and ( derivative action ) as integral and derivative constants. It has wider scope of design (White, 1997; Yang, 2006; Sampath Kumar, 2020; Samardzic, 2017; Murugan, 2020; Aroulanandam, 2019) this fractional order PID controller is a better solution for many industrial problems and some applications.
