Motion Control - The Future of Advanced "Intelligent Manufacturing"

In recent years, with the continuous improvement and improvement of motion control technology, as an independent industrial automation and control products, motion control system has become a mature technology, occupies a very important position in the automation industry; and in recent years integration including production Decision-making, integrated manufacturing, friendly man-machine, energy saving and environmental protection processing and global production decision-making, "intelligent manufacturing" has become an important trend of factory automation, of which motion control technology also plays a key role in which is also the future of advanced "smart" core .
As a part of automation, motion control technology in the strong market demand, driven by the rapid development of motion control technology, widely used. Almost all of the "actions" are related to motion control. Now more and more technology is integrated into the system, therefore, motion control is no longer just to control the "movement", "intelligent control" in the manufacturing role is also increasingly important.
In the 20th century, in advanced countries such as the United States, driven by a strong market, motion control technology has entered a phase of rapid development. Before the 21st century, the centralized control system dominated the world of automation design, and the motor was controlled by the host computer through the CPU. Whether pulsed Or communication, are issued by the command to affect the motor action, a password action to achieve the ultimate goal of the production line; but then with the PC system with the development of DSP and FPGA, but also allow motion control has entered a new phase.

With the development of automation and motion control technology to grow
Motion control originated in the early Servomechanism, basically a fairly historic technology. Simply put, the motion control is to control the position and speed of the mechanical moving parts in real time so that they can move according to the expected movement trajectory and the specified movement parameters. Early motion control technology was developed mainly with the development of CNC technology, industrial robotics and factory automation technology. As a result, the technology of motion control started to change as the system developed.
Motion control equipment, can be divided into two types of general-purpose and dedicated, universal system from the initial integration of motion modules through the PLC to PC-Based motion control card in recent years, the import of products, as part of the Department of Dedicated, is the CNC controller The two sides of the motion control system hardware development, have gradually peaked, coupled with the gradual production line complexity, the aforementioned two levels of motion control requirements, but also with the expansion.
Due to the complexity of the production line, coupled with the demand for "information integration" in the system, including the introduction of vision and database, as well as the introduction of manufacturing management systems such as ERP and MES, the above requirements for information integration by various controllers are also expanded , Letting the role of motion control in production online not only control the "movement" but also increase the need for system integration.
In addition, the rapid development of industrial robots in recent years has also brought about considerable qualitative changes in the technology of motion control. The integration of industrial robots and motion control systems with the establishment of a complete production line has also become an emerging topic of production online.
As the goal of motion control is to complete the production line of products manufacturing process, in the middle of the motion control process, in fact, is not the most important, but how can the correct real-time to meet the requirements, is the most important function; plus now all Product sophistication requirements are getting higher and higher, the process requirements are also more stringent, and pay attention to real-time and precision motion control, to achieve the best, you have to integrate a variety of related technologies, such integration is considered the most difficult Control Technology.
How to prepare is perhaps an important issue that automakers are currently facing. However, it seems that motion control has become more than just the control of motion, and has gradually become an important development aspect in process control.
