Abstract


The papers from the domestic and international the hydraulic excavators electronic energy - saving application status departure , the design hydraulic excavators electronic energy saving control system . Improved variable structure of single neuron adaptive PID control algorithm applied to the engine - variable pump power matching control , simulation results show that the algorithm has advantages . Single , dual variable pump system , hydraulic excavators single neuron adaptive PID control algorithm applied to a different system to study a single dual variable displacement pump and engine power to match the control strategy for variable structure will improve . At the same time , in order to solve the engine - variable pump power matching links with variable pump - load matching link between the uncoordinated design variable pump - load matching system handle position signal in accordance with the operator , the control variable pump output flow pro rata load hydraulic excavator engine - variable pump - load power match . Embedded computer control system is one of the focus of today 's single-chip control system . Embedded systems used in the electronic energy-saving control of the hydraulic excavator , select the ARM7 family processor LPC2294 as the core of this controller , power matching of hydraulic excavators electronic energy-saving controller design , the electronic energy-saving controller for hydraulic excavators research and development foundation.
