Control System Analyses Of Straight Pillared Electro-Magnetic Gears By Artificial Neural Network PID

With the science progress and the human civilization development, especially the slogan "green product" are advocated in recent years, people attach great importance to the new technique application day by day in the industrial production, and the magnetism application is more and more widespread. The electro-magnetic gears is a kind of non-contacts and non-pollution gearing electromechanical product, and it transfer power by magnetism coupling.This paper has summarized the development history and the present situation of the electromagnetism gear, and explained its drive characteristic,principle and structure . Using the empty displacement method and the Ampere circuital theorem analyzed the magnetic power calculation method of the electromagnetism gear drive organization. On this basis, by the analysis to the movement characteristic of the electro-magnetic gears , has arrived the calculation formula of the electromagnetism moment.Based on the ordinary gear drive model as the foundation, has set up the drivesystem dynamics model of the electro-magnetic gear, and carried on the simplification of the model under the certain supposition premise, As well as, deduced the relations between the input electric current and the output torque.In order to make the electromagnetism gear steady running, using the PID control method track the load change and adjust the coil electric current in time. Studied the PID controller structure of the BP neural network, analyzed the BP neural network study algorithm, and carried on the simulation realization in the Simulink environment of Matlab.This paper has offered some preliminary exploration for the further research work of the electromagnetic gear in the future and has certain reference value.
