Problems solved by technology

[0003] Unfavorable factors such as the multiple working conditions of the excavator's operating cycle, the external load changes, the proportional drive system faces strong external interference, the large inertia, high nonlinearity, and large lag of the transmission system make the engine work unstable
All of these make it very complicated and difficult to establish a mathematical model among the engine, variable pump and load

Abstract

The invention discloses a hydraulic energy-saving fuzzy control system for excavators, which comprises a fuzzy controller, a variable displacement pump regulator, a throttle controller, an engine, a pump and a pressure sensor; the fuzzy controller is connected with the variable displacement pump regulator, the variable displacement pump regulator is connected with the pump, the pump is connected with the pressure sensor, the pressure sensor is connected with the fuzzy controller, the fuzzy controller is also connected with the throttle controller, the throttle controller is then connected with the engine, and the engine is then connected with the pump. The hydraulic energy-saving fuzzy control system for excavators increases the energy transfer efficiency of the system, and reduces idle energy consumption inside a hydraulic transmission system.

Description

technical field [0001] The invention relates to the technical field of hydraulic excavators, in particular to a hydraulic energy-saving fuzzy control device for an excavator. Background technique [0002] Excavator, also known as excavating machinery (excavating machinery), is an earth-moving machine that uses buckets to dig materials higher or lower than the bearing surface, and loads them into transport vehicles or unloads them into stockyards. The materials excavated by the excavator are mainly soil, coal, sediment, and pre-loose soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of an excavator are: operating weight (mass), engine power and bucket capacity. [0003] Unfavorable factors such as the multiple working conditions of the excavator's op...
