摘  要:该文研究了一种以FPGA为控制核心,采用DSP与FPGA协同处理的基于旋转变压器的电动液压伺服无刷电机驱动系统的设计技术,并根据三冗余能源压力对电机实现宽范围的速度伺服控制,带动定量泵以调速方案对压力和流量进行实时动态控制,具有高转速、高可靠性和低能耗的特点,系统能耗降低了近50%,重量降低了近20%。The research of integrative servo driving technology of electro-hydraulic servo system uses the scheme of BLDC motor,which is based on the resovler to fit the harsh working condition.It uses the scheme of DSP and FPGA coprocessing together.The system varies the motor speed in a wide range depending on the three redundancy pressure signals,then the motor brings along a quantitative pump to compensate the changing pressure and flux.It has the characteristics of high speed,high reliability and low power consumption.The consumption is reduced by 50%,while the weight is reduced by 20%.
