摘　　要：为了减少电液伺服系统能源无用功的损耗和系统发热,介绍一种能源压力闭环控制算法。采用分段变增益调速和三冗余压力表决算法,实现能源压力闭环控制。建立了液压能源蓄能器数学模型和控制算法模型,通过了仿真分析和试验验证,表明控制算法有效,显著降低系统无用功的损耗和发热。A close-loop pressure control algorithm for a power supply in electro-hydraulic servo systems is introduced to reduce power supply loss and heating.A piecewise variable gain and triple redundancy pressure voting algorithm are used to implement the close-loop supply pressure control.The mathematical model for the hydraulic accumulator and the control model are presented,simulation and experiment performed.It shows that the control algorithm is effective to significantly reduce the power loss and therefore the generated heat.
