[Abstract]:With the rapid development of economy, science and technology and the continuous improvement of automation, material delivery system has been widely used in various industrial occasions. The traditional material delivery system is driven by the rotating motor through the transmission mechanism. The mechanical wear is serious and the noise is high, which leads to the low efficiency of the system and can not guarantee the reliability of the long-term operation. How to meet the high efficiency and reliable demand of material delivery system is a difficult problem to be solved. Under this background, this paper puts forward the idea of applying non-contact electromagnetic traveling wave driving technology to the material transportation system, and designs and develops the system model. The main research work is as follows: first of all, According to the requirements and specific conditions of the project, the overall design of the system is proposed. This paper introduces the structure, function, relay driving principle and positioning principle of the system, and puts forward the overall monitoring and bottom control scheme on the basis of expounding the electric structure of the control system. Secondly, the finite element method is used to analyze and optimize the electromagnetic traveling wave driver. This paper introduces the principle and steps of finite element analysis, establishes the two-dimensional model of electromagnetic traveling wave driver in ANSOFT environment, and simulates its static magnetic field distribution and dynamic characteristics. Aiming at the phenomenon of large thrust fluctuation, a method of reducing magnetic resistance by compensation method is put forward. The simulation and experimental results verify the effectiveness of the compensation method and optimize the driving performance of the electromagnetic traveling wave driver. Thirdly, the hardware and software of the underlying controller are designed and developed. A power drive circuit with intelligent power module (Intelligent PowerModule,IPM) as the core, a control circuit with the digital signal processor (Digital Signal Processor,DSP) as the core, and auxiliary circuits such as current detection and fault processing are designed. Based on the principle of sinusoidal pulse width modulation (Sinusoidal Pulse WidthModulation,SPWM), the three-phase current generation program, interrupt protection program and timing interrupt program are completed. Finally, the model of carrier system is designed and made, and the overall monitoring system based on programmable logic controller (Programmable LogicController,PLC) and touch screen is developed, and the system is debugged synthetically. The feasibility and effectiveness of electromagnetic traveling wave driving technology applied to material delivery system are verified.
