Some outside scholars using a nonlinear modeling method, and have achieved good results, but both the control system itself or its controller design process, in general more plex, a large part of the workload are concentrated in the control algorithm itself theoretical derivation and to implement the greater the difficulty, high cost, but also affect the reliability of the system, so they need a reasonable modeling of the system. Over the past decade, the general trend of development of the hydraulic excavator is to improve the reliability and efficiency, reduce costs, continue to the development of largescale miniaturization。s main control valve function type can be divided into opencenter load sensing system (opened center load sensing system, OLSS) and closed center load sensing system (closed center the load sensing system, CLSS), the median function (open, closed) resulted in a different form of the load sensing control system. diversion control methods and more sensitive system to perform a Load 16 J include: (1) based on the priority pressure pensated shunt control The concept of priority pressure pensated in 1969 by J. D. The A11, ell, the specific method is still to achieve a maximum speed of the actuator (such as hydraulic power steering, etc.): For the case even in the prime mover speed is very low or loads, in order to ensure that its flow to it than the high priority, and allows each actuator in the pump displacement is insufficient according to the priority from low to high order to reduce the speed. Such a priority pressure pensated the role of valve, called the priority valve. Composite operating system with priority pressure pensated, it is possible to produce a low priority execution to stop working. In order to lower priority execution does not stop even in the case of a serious foot pump output flow movement, and sometimes need to weaken the priority of this pressure pensation. This pressure differential pressure across the variable orifice pensation. (2) pensation based on the split ratio adjustable pressure shunt method In some machinery like hydraulic excavators need to make each actuator speed to maintain a certain ratio to ensure that the coordinated action of all actuators, can not be in the actuator attach priority.
