摘　　要：为应对电枢出口速度需要进行灵活以及精确调节的场景,提出了一种使用异步式线圈推进器作为主加速装置,同步式线圈推进器在尾部作为调速器进行速度控制的联合调速方案.在ANSYS中建立了将调速器放置于单段异步式线圈推进器出口的二维仿真模型,针对调速器的实体设计,分别对异步式推进器最后一匝线圈与同步调速器线圈间距离和调速器线圈长度进行了仿真分析;使用该模型验证了改变脉冲电源初始电压能够控制调速器调速范围,以及改变开关触发时间能够控制调速器实现需求的电枢速度补偿,进一步给出控制回路的设计方案,为电磁线圈推进尾部电枢速度控制应用奠定了理论基础.In order to cope with the situation where the armature exit speed needs to be adjusted flexibly and precisely,this paper proposes a joint speed regulation scheme which uses an asynchronous coil launcher as the main acceleration device and a synchronous coil launcher as the governor at the tail for speed control.A two-dimensional simulation model of placing the governor at the exit of the single-segment asynchronous coil launcher is established in ANSYS.The distance between the coil of the last turn of the asynchronous launcher and the coil of the synchronous governor as well as the length of the coil of the governor are respectively simulated and analyzed for the physical design.The model is used to verify that changing the initial voltage of the pulse power supply can control the speed range of the governor,and changing the trigger time of the switch can control the governor to achieve the required armature speed compensation.The design scheme of the control loop is further given,which lays a theoretical foundation for the application of tail armature speed control in electromagnetic coil propulsion.
