Simulation of Active Magnetic Bearing Response based NNC

Abstract

The present work is dealing with the modeling, investigations, and controlling, of a prototype radial magnetic bearing system. Considerations based on the 8 poles model with switched mode power supply. Investigations of radial forces in two axes model and performance response are carried out through the intelligent controller system. Improving system response is achieved by using an efficient controller based Neural Network (NN) NARMA-L2 Controller together with the conventional PID controller. The response is presented for stand still and dynamic conditions using the implemented Simulink software. The results show that the NARMA-L2 is highly improved the dynamic response of the speeding up rotor in comparison with the conventional controller. ‫ﺘﻤﺜﻴل‬ ‫ﺍﺴﺘﺠﺎﺒﺔ‬ ‫ﺍﻟﻤﻐﻨﺎﻁﻴﺴﻴﺔ‬ ‫ﺍﻟﺭﺍﻓﻌﺎﺕ‬ ‫ﺍﻟﺼﻨﺎﻋﻴﺔ‬ ‫ﺍﻟﻌﺼﺒﻴﺔ‬ ‫ﺍﻟﺸﺒﻜﺎﺕ‬ ‫ﺒﺎﺴﺘﺨﺩﺍﻡ‬ ‫ﺍﻟﺨﻼﺼﺔ‬ ‫ﻟﻸﺤﻤﺎل‬ ‫ﻤﻐﻨﺎﻁﻴﺴﻲ‬ ‫ﻟﺭﺍﻓﻊ‬ ‫ﻤﻘﺘﺭﺡ‬ ‫ﻨﻤﻭﺫﺝ‬ ‫ﻋﻠﻰ‬ ‫ﻭﺍﻟﺴﻴﻁﺭﺓ‬ ‫ﻭﻤﺤﺎﻜﺎﺕ‬ ‫ﻨﻤﺫﺠﺔ‬ ‫ﺍﻟﺒﺤﺙ‬ ‫ﻫﺫﺍ‬ ‫ﻴﺘﻨﺎﻭل‬ ‫ﺍﻟﺩﻭﺍﺭﺓ‬ ‫ﺍﻷﻓﻘﻴﺔ‬. ‫ﺍﻷﻗﻁﺎﺏ‬ ‫ﺜﻤﺎﻨﻲ‬ ‫ﻋﻥ‬ ‫ﻋﺒﺎﺭﺓ‬ ‫ﺍﻟﻤﻌﺘﻤﺩ‬ ‫ﺍﻟﻨﻤﻭﺫﺝ‬ ‫ﻤﺘﻁﻭﺭ‬ ‫ﻗﺩﺭﺓ‬ ‫ﻤﺠﻬﺯ‬ ‫ﺫﺍﺕ‬. ‫ﻤﺴﻴﻁﺭ‬ ‫ﺍﺴﺘﺨﺩﺍﻡ‬ ‫ﺘﻡ‬ ‫ﺍﻷﺴـﺘﻘﺭﺍﺭ‬ ‫ﺤﺎﻟﺔ‬ ‫ﻓﻲ‬ ‫ﺍﻟﻨﻤﻭﺫﺝ‬ ‫ﺍﺩﺍﺀ‬ ‫ﻭﻜﺫﻟﻙ‬ ‫ﺒﺎﻟﻤﺤﻭﺭﻴﻥ‬ ‫ﺍﻟﻨﺎﺘﺠﺔ‬ ‫ﺍﻟﻤﻐﻨﺎﻁﻴﺴﻴﺔ‬ ‫ﺍﻟﻘﻭﻯ‬ ‫ﻭﻤﺤﺎﻜﺎﺕ‬ ‫ﻟﺩﺭﺍﺴﺔ‬ ‫ﺫﻜﻲ‬ ‫ﻭﺍﻟﺤﺭﻜﺔ‬. ‫ﺍﻟﻤﺴﻴﻁﺭ‬ ‫ﺍﻭ‬ ‫ﺍﻟﺫﻜﻲ‬ ‫ﺍﻟﻤﺴﻴﻁﺭ‬ ‫ﺍﺴﺘﺨﺩﺍﻡ‬ ‫ﺍﻥ‬ ‫ﺍﻟﻨﺘﺎﺌﺞ‬ ‫ﺍﺜﺒﺘﺕ‬ ‫ﻟﻘﺩ‬ ‫ﺒﺎﻟـﺸﺒﻜﺔ‬ ‫ﺍﻟﻌـﺼﺒﻴﺔ‬ ‫ﻗـﺩ‬ ‫ﺃﻋﻁـﻰ‬ ‫ﻓﻲ‬ ‫ﺠﻴﺩ‬ ‫ﺘﺤﺴﻴﻥ‬ ‫ﺍﻻﺴﺘﺠﺎﺒﺔ‬ ‫ﺍﻟﺤﺭﻜﻴﺔ‬ ‫ﻭ‬ ‫ﺃﺩ‬ ‫ﺍﺀ‬ ‫ﺍﻟﻤﺴﻴﻁﺭ‬ ‫ﺍﺴﺘﺨﺩﺍﻡ‬ ‫ﺤﺎﻟﺔ‬ ‫ﻋﻥ‬ ‫ﺍﻟﻤﻨﻅﻭﻤﺔ‬ ‫ﺍﻻﻋﺘﻴﺎﺩﻱ‬ 1047 PDF created with pdfFactory Pro trial version www.pdffactory.com
