Network induced delay of asynchronous motor connected to Profibus-DP networks using fuzzy logic control algorithm

摘要

In this study the remote control of an asynchronous motor (ASM) was performed by fuzzy logic. The study is substantially in the form of Profibus-DP network structure, ASM and fuzzy logic control (FLC). The aim of the study is to reduce the network-induced delay by the help of fuzzy logic algorithm and high speed data transfer feature of the Profibus-DP network structure. Also, the designed system was controlled by Proportional-Integral-Derivative (PID). Findings related to PID were compared with FLC. By the builded structure, the network-induced delay, the reaction time of the motor during remote control and the effect of the fuzzy logic algorithm in the application has been examined. The experimental analyses have been graphically presented. In these graphs, the network-induced delays have been presented by the structures in which only Profibus-DP network with PID was used firstly then the structure with FLC respectively.
