Control system and control method of reluctance motor for rapier loom spindle

Abstract

The invention discloses a control system and a control method of a reluctance motor for a rapier loom spindle. According to the control system, an embedded control technology is applied, an STM32 single-chip microcomputer with a high function integration level serves as a core for the first time, hardware circuits of all function modules are designed to serve as a loom main shaft driving control core, the integration level is improved, the control cost is reduced, and energy consumption is reduced; and a hardware architecture based on a bus structure can be used for conveniently expanding system functions, so that the flexibility is higher and the working efficiency is higher. According to the invention, a single neuron fuzzy PID speed control strategy based on voltage chopping control and fuzzy control multi-algorithm fusion is provided for the first time to improve PID parameters and adjust SRM speed, so that driving control of the loom spindle is realized. The algorithm has better dynamic response performance and dynamic characteristics, so that the starting performance is stronger, the working efficiency is higher, the cost is lower, the energy consumption is lower during driving control of the loom main shaft, and the actual industrial production requirements can be better met.

Description

technical field [0001] The invention relates to the field of a rapier loom control system and a control strategy, in particular to a control system and a control method of a reluctance motor for a main shaft of a rapier loom. Background technique [0002] With the improvement of the level of my country's textile industry and the growth of product exports, looms, as the most important weaving equipment in textile equipment, have a large demand in the textile industry. Judging from the development of foreign rapier loom technology, great changes have taken place in mechatronics, speed, selection and other technologies, but there is still a big gap between domestic loom equipment and foreign countries, especially in rapier looms. machine-integrated control system. Therefore, it is of great value and significance to improve, develop and enhance the performance of the domestic rapier loom control system. [0003] At present, the speed of domestic rapier looms has reached a rela...

AI Technical Summary

Problems solved by technology

General Electric equipment has high reliability and stability, strong anti-interference ability, short development cycle, and the research and development process is similar to building blocks, which is easy to cause redundancy and waste of functions, and the high-end PLC market is basically monopolized by foreign manufacturers, and the cost is high

The literature "Ye Taiqiang, He Yong, Shen Xiaoqi, et al. Design of Rapier Loom Control System Based on STM32F4 Embedded [J]. Automation and Instrumentation, 2019, 34(03): 9-13." proposes to use two STM32F4 microcontrollers as the core The control system divides the system into five sub-modules, but does not consider the direct drive of the spindle and the network upgrade of the system, and still uses general electrical equipment such as frequency converters. The integration level is low, resulting in redundant and wasteful functions and high costs.

[0007] 2. Spindle direct drive technology is not popular

Due to the limitations of asynchronous motors, most domestic looms still use the indirect transmission structure of pulleys combined with clutches. The structure is complex, which increases the daily maintenance burden of looms, weak start-up performance, low work efficiency and high energy consumption.

The control system of rapier loom with 16-bit single-chip microcomputer P51XA-S3 as the core proposed in the literature "Wang Yinghui. Design of automatic control system for high-speed rapier loom [J]. Textile Report, 2020,39(06):17-19." , can support a maximum spindle speed of 600 rpm, but also has problems such as complex structure, low work efficiency and high energy consumption

[0008] 3. The degree of intelligence and informatization of the loom is not high, and the scalability is poor

Due to the limitation of hardware structure and interface, if the existing loom control system needs to be modified, it is likely to need to replace the entire control system, which increases the difficulty and cost of system upgrade

The paper "Wang Shu, Wu Xiaoyan. Research on Rapier Loom Monitoring System Based on TwinCAT& The basic design of the control and monitoring system uses EtherCAT to coordinate the lower computer to control the operation of the loom, but the system needs to use PC as the software operating platform, which has relatively large limitations.
