Experimental verification of design methods for conventional PI/PID controllers

Abstract

Článek se zabývá experimentálním ověřením metod návrhu pro konvenční PI(D) regulátory.

The paper presents an experimental verification of conventional PI and PID controller design methods. Nine different synthesis techniques were used to control of airflow speed in laboratory model of hot-air tunnel, most of them for both PI and PID version. In the first instance the controlled plant was identified in order to obtain a linear mathematical model and then the controllers were designed using studied methods. The controllers were tested in simulations and subsequently implemented under real conditions. The obtained control results have been compared and analyzed.
