[Abstract]:Industrial seaming machine is a kind of equipment used to sew in the textile and garment factories. Its structure is complex and the servo control technology is difficult. For a long time, the servo controller of the electronic control industrial slit machine used in China is basically imported from abroad. The corresponding research and development in China is late and the technical level is not high, so the high performance electronic control package is made. The machine is only a luxury for a few high-end garment manufacturers. The continuous and rapid development of the domestic textile and garment industry has brought great opportunities for the development of the sewing equipment industry, and the performance of the sewing machine is determined by its servo control system. When the high performance servo system should be used in large-scale factory production, it can be reduced. The light labor intensity greatly improves the production quality and production efficiency. Therefore, it is of great significance to develop a high performance servo control system for the slit machine. In order to develop the servo system for the industrial use of the slit machine, this paper takes into account the performance index of the servo system on the basis of the study of the working mechanism of the industrial slit machine. The main work of this paper is as follows: (1) the theoretical research of AC servo control system, including the mathematical model of permanent magnet synchronous motor, vector control technology and voltage space vector pulse width modulation technology, is the main work of this paper. The design of the servo system for the slit machine is designed and the hardware and software design provides the theoretical basis. (2) the selection of the servo motor is analyzed. According to the performance requirements of the slit machine, the position, speed and current three closed loop control strategy are designed. In order to realize the accurate servo control, the rotor position detection method and speed of the servo motor are determined. At the same time, the simulation study of the motor closed loop vector control system is carried out. The intelligent PID controller based on artificial bee colony algorithm is used to design and simulate the speed loop. The optimization mechanism of the artificial bee colony algorithm is fully utilized to improve the speed control performance of the motor. In addition, the braking control scheme of the servo system of the slit machine is also carried out. Design. (3) to design the hardware of the industrial seaming machine servo system, the DSP chip tms320f28034 of Ti is used as the core controller, and the external circuit is connected with the other parts of the servo system through multiple interfaces. The current sampling circuit, the bus voltage sampling circuit, the speed and the position detection circuit are designed, and the power of the power is designed. Rate driven chip is selected, other peripheral circuits such as foot pedal speed control circuit, solenoid valve drive circuit and electric eye sensor circuit are designed. (4) the design of the servo system software for industrial slit machine is designed, the CCS integrated development environment of Ti is used to develop software, and the event driven programming architecture is used for the servo system of the slit machine. The software state block diagram and the system software state machine are designed in detail. At the same time, the algorithm flow chart of the module is given for the motor vector control algorithm. The software design of the failure processing module of the slot machine system is designed, and the key and display part of the operation panel are designed. Finally, the developed seaming machine servo system is developed. The test results show that the developed servo system meets the needs of industrial application and has a good prospect of industrial application. At the same time, the full text is summarized and prospected, and the direction of further research is put forward. The main innovations of this paper are as follows: (1) the artificial bee colony algorithm and the PID controller phase are innovatively. Combining, and designing the fitness function containing the overshoot penalty item, the stochastic optimization mechanism of the artificial bee colony algorithm is applied to the optimization process of the motor speed loop control parameters. The simulation results show that the motor speed control effect is better. (2) in order to realize the auto start stop of the edge sewing process, two pairs of electricity are added to the seaming machine servo system. The eye sensor, according to the detection condition, determines whether the cloth is under the lifting pressure foot, realizes the automatic detection of the position of the cloth, automatically raises the function of the lifting and lifting feet, and effectively improves the automation of the servo control system. (3) in order to ensure the clean environment of the industrial processing site, two air suction electromagnet modules have been added to the control system. Through the control of the electromagnet and the pneumatic suction device, the broken wire and the broken material produced during the sewing process are inhaled into the specified bag, which effectively keeps the cleaning of the industrial processing site.
