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.

As a flexible AC transmission system equipment, controlled shunt reactor is becoming increasingly important in the grid with the development of EHV / UHV transmission systems. Since currently rated voltage of controlled shunt reactor has developed to 1100kV, as its capacity control system, or valve-control system, stability and reliability test is very important. In this paper, the test circuit and method for the valve-control system in the laboratory or the test station for combined adjustment test is put forward. By adjustment of power supply and the device parameter, the valve-control system can put the voltage and current of the device to be the same as the on-set operation. Actual test of the world's first 1100kV controlled shunt reactor valve-control system shows that, the test method in this paper is correct and feasible, and the objective of assessment can be achieved.

This article describes the design of an articulation robot arm with seven joints. The control core of the robot arm is the module-based system built using the Mitsubishi Q series programming logical controller (PLC). The robot arm contains seven AC servomotors, seven driver devices, a vision system and a PLC control system. The PLC-based controller programs the motion trajectory of the gripper to catch or hold the objects and finish the assigned tasks. Kinect system (Asus Xtion Pro-Live, or called RGB-D sensor) acts as the vision system to recognize shape and color of each object. During the experiments, we found that the robot arm recognizes the shape and color of each object, and catches each object moving to the assigned box with the same color.
