The Research Of Self-synchronous Vibrating Fixed Quantity Feeding System

With China's rapid development of industrial production, feeding equipment, as many production equipment feeding system has been widely used in metallurgy, building materials, electric power, chemicals, food, medicine and other industries. This paper will be conducted quantitative self-synchronization vibration feeder system for use in industrial ingredients, mainly to solve the application of the PID algorithm from the traditional synchronous vibration control system for materials research.In this paper, the quantitative feeding system loop control on classification, and the quantitative composition of feed system, the principle of self-synchronization vibrating feeder and characteristics were analyzed. At the same time on the instantaneous flow and the method of calculating cumulative flows were analyzed. Since the synchronous motor and the inverter vibrating feeder models also choose a calculated and the corresponding note.This paper focuses on the feed control system hardware and software design. The hardware system based on 8-bit MCU AT89C52 for design, development, use analog filtering technology. Before and after the selection of a design to channel 12-bit A/D and D/A converters to ensure that the control precision. Motor gun photoelectric encoder using isolation techniques, the output of the input to avoid the interference. Selection of non-volatile data storage system after brownout guarantee an important parameter not lost.12 digital control can be shown instantaneous flow value of cumulative flows, flow settings, such as PID parameters of a number of parameters. Keyboard parameters of the PID system to feed parameters, such as timely creation and revision. And the application of Advantech IPC on the onboard configuration software, design parameters PID controller control panel Fig. System software control algorithm uses PID control algorithm to overcome the effective regulation of the flow deviation, the slow oscillation. This paper proposes using fuzzy self-tuning controller vibrating feeder on the self-synchronization control. MATLAB simulation tools and the use of fuzzy self-tuning PID controller of a preliminary study. The simulation results show that, obviously superior to conventional PID control, a small amount of overshoot, and the transition time is short, good stability, adaptability, and other characteristics to achieve the desired control results. Through PID control system in the quantitative vibration feeder system applications, Since the synchronous vibration verified feeder system as a constant feed the feasibility of control, speed control accuracy and control to meet the requirements of a number of occasions. At the same time, conventional PID controller and fuzzy self-tuning PID controller simulation compared to prove that fuzzy self-tuning PID control to further enhance accuracy.
