Study on Relationship of Intellectualization between Hydraulic Mobile Machinery and Hydraulic Components

This paper analyses the current situation of insufficient intellectualization of hydraulic system and component in the process of intellectualization of Engineering robots, and puts forward the way to develop hydraulic intelligent components. At the present the hydraulic intelligent components are still in the initiation period, the main requirements and means of product development are put forward in this paper. Emphasis is laid on the feasibility of implicit state space method as the core theory of hydraulic intelligent components, and a control algorithm of hydraulic components based on implicit state equation is proposed, which can realize the function of autonomous control. A parameter identification method based on the inverse operation of the above control algorithm is proposed, which can be used to construct a model-based intelligent fault diagnosis system for grey box identification, and for future use in the hydraulic technology. Fault diagnosis of hydraulic system and components are prospected. Hydraulic intelligent components are to be an agent. It continues to develop in application in intelligent construction machinery, and will inevitably open up a new practical application market in the development of digital twin technology.
