Objective: The cotton textile industry, as a competitive industry in China's international competition, is confronting new opportunities and challenges brought by the growing process of mechatronics. To further improve the traditional drive control of combing machines made in China and the automatic level of machines as a whole, some of our cotton textile enterprises have undertaken necessary technical transformations on the combing machines so as to raise the operational efficiency and production technology of domestic textile equipments. Methods: This paper focuses on the basic status and dynamic characteristics of the drive part of the domestic new comber, and analyzes the operation process of the comber and the prominent problems from the production practice. Results: The technically improved drive control system uses an industrial control computer (IPC) as the core of the system, which effectively improves the overall working efficiency of the comber, and improves the production accuracy and production efficiency. Conclusion: The combers that are textile machinery equipments with comprehensive application of machines, electricity, gases and instruments, play a vital role in enhancing product quality and production efficiency. Highly intelligent and integrated process control, real-time monitoring and accurate data acquisition and data analysis have become the mainstreams in the development of auto-control. Therefore, the commitment of high technology to transform the traditional production mode has also been an important research.

We preliminarily designed a power tracking and control system using single-chip computers and industrial control computer in the electric heating simulated power loop. The system is an innovational design based on the proven simulated nuclear power loop, with increased techniques of step-less power regulation system and modeling nuclear feedback effect correctional programs. We promoted both hardware and software designs of this power tracking and control system in this paper. It used single-chip computers as the core control chips and an industrial control computer as the additional correctional program and record carrier. The process and implementation of the control software are presented, which is designed as a fuzzy theoretical nonlinear system. In order to ensure the subsequent updates, the access interface of the system is open for following correctional programs, including the correctional program of void fraction effect, temperature effect, hysteresis effect and heat power distribution effect. Taken hysteresis effect correctional program as an example, we use an offset tic-tac clock replacing the inherent tic-tac clock in different devices of the system in order to reduce the hysteresis effect of measuring and corresponding errors. We also put out a preliminary analysis of the accurate synchronization for the system at the end of the paper.

Final testing procedures are performed to assure the quality of manufactured parts before their shipping to customers. Turret based test handler is a general kind of IC Test Handler for final testing. This paper discusses how to develop a general control system for a test handler of turret style in which every workstation moves up and down separately based on an industrial control computer. The combination of object-oriented programming and the cycling scanning working mode is the key of the whole system. To achieve ideal performance, special control flags are designed as an efficient way for making all the workstations work as setting orders stably. The method to developing the control system in this paper can be also applied to similar systems, which would greatly reduce development cycles. A turret based test handler with this control system has passed the test of a semiconductor factory and operates well in actual production.

The levels of continuous casting process of copper and copper alloy billet have many advantages, such as taking small footprint, low investment and the shorter flow. Recently, it develops very quickly all over the world. This article designs the dummy body drive control system based on the DSP digital signal processing chips, inverter and variable speed induction motor, and uses the unique process that space vector pulse width modulation strategy can achieve continuous casting horizontal tractor’s four beats to realize continuous casting process’ high-quality, stable and reliable implementation. Early in the 19th century, German Bismarck had proposed a continuous casting process in his patent. The development of this method in the copper industry began in 1940s, the type of equipment went through belt type, vibration mold, vertical traction type, tilt casting type and Horizontal traction type [1, 2]. Now, horizontal traction, as the most popular method abroad, because its products don’t need straightening, and consistency of properties along the length and high density of grain lead to the improvements of mechanical properties and electrical properties, its superiority in product quality and production efficiency is obvious. The design combined the modern AC variable speed control and advanced SCM control technology and traction continuous casting process to design a Speed controller of horizontal continuous casting of copper traction motor, its performance is similar with to dummy industrial control computer and AC servo motor drive control system, but the configuration of the hardware is less than half the price.
