摘　　要：近年来,伺服系统广泛应用于数控机床、工业机器人、电子制造等领域,其中的脉冲负载工作时呈现常态低功率、瞬间高功率的特点,并伴随反灌制动能量,这种固有特性会影响系统的稳定性。为应对这些挑战,文章研究并设计应用于伺服系统的复合电源。在该复合电源中,储能电容通过双向能量补偿器与电池并联,为伺服驱动器负载供电。这种方法可以实现输入与输出侧功率解耦,继而抑制母线上电压波动。此外,文章利用交错并联式Buck/Boost拓扑结构减小了电流纹波,并且针对此结构的双向能量补偿器提出一种状态辨识控制策略。利用脉冲负载状态辨识算法检测脉冲负载的状态,根据不同状态来选择对应的控制回路。通过实验分析,验证了双向能量补偿器工作状态良好、复合电源工作正常。In recent years,servo system has been widely used in CNC machine tools,industrial robots,electronic manufacturing and other fields.The pulse load has the characteristics of normal low power and instantaneous high power,accompanied by backward braking energy,which will affect the stability of the system.In order to meet these challenges,this paper studies and designs a compound power supply for servo system.In this compound power supply,the energy storage capacitor is connected in parallel with the battery through a bidirectional energy compensator to supply power to the servo driver load.This method can decouple the input and output power,and then suppress the voltage fluctuation on the bus.In addition,the staggered parallel Buck/Boost topology is used to reduce the current ripple,and a state identification control strategy is proposed for the bidirectional energy compensator with this structure.The pulse load state identification algorithm is used to detect the pulse load state,and the corresponding control loop is selected according to different states.Through experimental analysis,it is verified that the bidirectional energy compensator works well and the composite power supply works normally.
