About precision hydraulic control, most people will think of the servo valve, sensor, closed-loop feedback, automatic control, transfer function, frequency response and so on theory, algorithm. These integrated mechanical, fluid mechanics, electrical, automation, computer, measurement, and even materials, technology, and many other disciplines of modern science and technology, who will be able to master so many science and technology? Therefore, the development of hydraulic technology difficult.

Who studied the principle of simple, low cost, safe and reliable, practical and convenient toilet? Yes, flush toilets! Three key components: float lever, cone valve, to achieve the precise level (volume control). How easy it is to be a simple, effective, inexpensive and reliable mechanical feedback control device that replaces the complex modern science and technology!

Simple solution is the best.

Since the last century at the end of 70s, AEMETEC Co., Ltd. founder professor Yang Shixiang started the research of digital hydraulic technology, in early 80s issued the first domestic China article on digital hydraulic research, 1983 Chinese authoritative academic journal "hydraulic and pneumatic" published. In 1989, the first generation of digital hydraulic cylinder that is applied to the national key projects. Professor Yang continued to promote the development of digital hydraulic technology to overcome its shortcomings and 

deficiencies, the second generation, the third generation of technology have been born and successfully applied to important national key engineering applications.After nearly forty years of continuous efforts, and now the digital hydraulic has formed a series of products and a large number of applications in many fields, including: national defense, metallurgy, energy, machinery manufacturing, etc., In addition to the traditional hydraulic components, proportional hydraulic and servo hydraulic technology, digital hydraulic has become a reliable performance, high precision, design, installation, commissioning and maintenance are very simple new technology. Digital hydraulic pressure has been favored by many users. In recent years, with the development of information technology and the rise of intelligent manufacturing, as the core part of transmission, the development of digital hydraulic technology has been paid more and more attention. In 2016, the national "13th Five-Year" hydraulic industrial development plan included AEMETEC's 7 series digital hydraulic technology, digital hydraulic pressure caused by both academia and industry. In early 2015, the origin, development and technical features of digital hydraulic pressure were discussed on the internet. In August 2016, the characteristics of digital hydraulic technology are further discussed. In order to objectively describe the characteristics of AEMETEC's digital hydraulic, we talk about ourself views.
