Investigação de um controlador PID baseado em uma metodologia fracionária aplicado na regulação de velocidade de um sistema de 2kVA

Abstract

In this work, automatic control techniques are investigated, using the most efficient Electric Power System to improve the speed governor performance of hydraulic turbines. For this purpose, a controller based on a fractional calculus methodology is tuned, as this method has a greater degree of freedom in the realization of projects. For the tuning of the controllers, the dynamic model of the 2kVA small scale generation system was used. Initially, the two controllers are tuned in the computational environment, being them, or the fractional order PID controller (FOPID), based on an analytical method of calculating methods from the gain and phase margin values and, the classic controller, designed by the conventional pole allocation method. Subsequently, how control laws are implemented as a digital control in an embedded system using the Arduino Due microcontroller. The behavior of the controllers is evaluated both through simulations, through MATLAB/Simulink and by conducting experimental tests related to the speed governor reference variation of a 2kVA micromotine. In view of this, you can match or perform FOPID controller performance with controller via pole allocation.
