Electromechanical Drive Control Learning Note 1

1. Modern electromechanical control system for engineers required capacity requirements

In the reading material, 1.3 reads, "In the face of a rapidly changing world, proficient in many disciplines, good at learning and innovation, with good team spirit and communication skills, these are the basic quality requirements of engineers." "Value competition consciousness", "standardization and Standardization", "innovation and learning" have been carefully explained. Of course, these quality requirements are also part of the capacity requirements, which is more attractive to my eye is "many disciplines."

These requirements for engineers are based on the problems faced by global manufacturing automation, mainly in the digitization of globalization and the shortening of the product life cycle as well as the increasingly close links between technology and limited resources.

In this age of big data, any service to the public is almost always a result of teamwork, and the automation of a mechanical system requires knowledge of a multidisciplinary combination of knowledge such as material science, mechanics, and computer science, which not only requires that each engineer have at least a little understanding of these subjects, Engineers with different expertise are also required to effectively exchange lumped opinions to produce a complete control scheme. Mechanical design in the direction of Mechatronics has made it possible for engineers to have a multidisciplinary knowledge and to work together in a good way.

Innovation is a necessary quality, is to promote the progress of all human causes of the quality. The integration of multi-disciplinary knowledge, multi-engineer collaboration has also increased the possibility of innovation, the speed of technological development has forced us to continue to learn and progress.

The limited resources also greatly affect our design of automation. Limited manpower, limited energy, limited time, limited raw materials require us to find a balance between cost and efficiency, labor costs and personnel quality needs to be measured, the design of the machinery to try to save energy and high output, and save raw materials, if recycling can be recycled waste can be, Efficiency can save time and speed up feedback to users. The simulation of the original understanding using the software saves the material and saves time. It is the general trend of electromechanical soft integration. And all of this is part of the multidisciplinary requirements that our engineers put forward.

Engineers with a lot of expertise and ability to exchange views on the rational division of Views friction and software simulation of a set of energy-efficient low-cost high-yield mechanical and electrical control scheme of the screen, I read the material after the modern engineer should have the ability of the intuitive idea.

2. Your status and direction of work

As a junior student, I currently have the practical experience is not many, but in the team to see others do some control aspects of the content, in the design of the time also basically did not consider the cost, just according to the seniors of the material use habits of choice materials, but actually do not understand the reason. We have to say that the cost of the college students now consider a little less, because the theoretical knowledge of learning more and the market is not concerned about the actual situation, contact raw materials market opportunities are relatively small. So I might need to know more about the market and find out more about what's in the project.

On the other hand is the ability to innovate, in fact, I have the pursuit of innovation, but have to admit that the limited knowledge and multi-disciplinary knowledge of the gap limit the ability to innovate, in the case of continuous pursuit of innovation I need more to combine the content of multiple disciplines to see if there will be a surprising fusion.

Teamwork is the course of study in the various courses often asked us to do things, I feel that their ability to collaborate has been a certain improvement, of course, know more people inspire all the potential of the team is the ultimate goal.

3. Expectations and learning plans for this course

The introduction says the task of this course is to make the whole factory automation, through the control of production yield, cost reduction, labor saving, energy, "according to the development of discipline and internal law, servo drive system as the leading, to control as the clue, the components and servo control system scientifically, organically assembled together, That is, the electrical and mechanical integration needs of the strong electrical control knowledge are concentrated in this course ", so I think this is a multi-disciplinary knowledge of a higher degree of integration, compared with the actual study of the basic disciplines more closely related disciplines, So I hope that through this course I can have a better understanding of mechanical knowledge and let this knowledge help me to better complete the project of the team, and think of becoming a good engineer to take a new step.

The study plan does not seem to be specific to the timetable, but the current plan is to follow the fundamentals of mechanical and electrical knowledge learned prior to the textbook review, to truly understand the principles of the various control systems, and to understand the content of the software that the teacher may teach in advance. And, of course, preparing for the course design that the course requires us to do. is generally a course of knowledge blending and sublimation.

4. Main points of interest and learning difficulties in the first three chapters

The second chapter of the textbook is the basic knowledge of dynamics, involving torque, inertia, load characteristics and time constants, quickly browse to find it is not difficult to understand, let me be surprised that the third chapter on the DC motor so much space to explain, after reading to find themselves before the superficial understanding of the linear motor is a bit ridiculous. Understanding the difficulty of the place naturally aroused my interest, so my point of interest is I feel the learning difficulties. It can be seen that the third part of the motor and the image combination is very close, so I think the recognition of the image and the characteristics of the motor and the image of the understanding is a difficult point, four kinds of motor (he excitation, and excitation, string excitation, complex excitation DC generator) identification is also a place to pay attention. A deep enough understanding of the image speed and braking should not be difficult, so the key is the image.
