“…When using multiple switching valves per metering edge the malfunction of one switching valve can be compensated by the others with just a small reduction in performance (Siivonen et al, 2009). Never the less, the higher number of components in a digital hydraulic system may lead to a higher probability of faults.…”

In this paper a novel and validated model to describe the dynamics of switching valves is presented and used to analyse the behaviour of switching valves. The paper starts with a brief discussion of the state of the art and the characteristics of switching valves, continuing with investigations of their dynamics, the development of the novel model and an analysis of the characteristics of switching valves based on the introduced model. The different operation modes which appear when fast switching control signals are applied are introduced and discussed. Additionally the application of the proposed model in closed loop simulations is pointed out and compared to state of the art models. It is demonstrated that the novel model offers a good trade-off between model accuracy and model complexity.

“…After that, the team carried out a series aimed at the control strategy [26,27], pressure peak [28], fault detection [29] and energy saving [30,31] of DFCU. And they successfully applied the DFCU to a paper cutting machine; it is superior to the traditional hydraulic system in terms of cost, control performance and energy saving [32,33].…”

Since the emergence of digital hydraulic technology, it has achieved good results in intelligence, integration, energy saving, etc. After decades of development, and it has also attracted wide attention in the industry. However, for many years, the definition of digital hydraulic technology has differed between researchers, and there is no uniform definition. Such a situation affects the development of it to a certain extent. Therefore, this paper gives the exact definition of digital hydraulic technology based on a large number of researches on it. At the same time, the paper analyzes the research status and developmental process of the such a technology, and we forecast the development trend of it.

“…The development of those creates the possibility of higher internal tightness and greater speed of control, and the ability to build special systems for large capacities of the volumetric flow rate, even several thousand liters per minute [11][12][13][14]. The logic valves are relatively new solutions, which are being systematically introduced to hydraulic controls and drives.…”
