摘　　要：针对传统火炮复进机中维护难、不易控制等问题,提出一种圆筒型永磁直线电机的新型电磁复进机。初步设计了新型电磁复进机结构,建立直线电机有限元模型,分析直线电机的推力特性,并得到电机的具体参数。利用Matlab/Simulink建立了直线电机的数学模型,运用有限控集模型预测控制算法(FCS-MPC)对复进机进行了控制。仿真结果表明,所设计的电磁复进机满足火炮复进过程的推力需求,模型预测控制算法的响应速度快,能够快速准确地使炮身复进到射前位置,并能在不同射角下维持炮身处于待发位置。In order to solve the problems of difficult maintenance and control in the traditional artillery recuperator,a new type electromagnetic recuperator based on the principle of tubular permanent-magnet linear synchronous motor(TPMLM)was proposed.The structure of the new type electromagnetic recuperator was preliminarily designed,and the finite element model of the linear motor was established,and the thrust characteristics of the linear motor were analyzed.The specific parameters of the motor were obtained.The mathematical model of linear motor was established by using Matlab/Simulink,and the finite control set model predictive control(FCS-MPC)was used to control the recuperator.The simulation results show that the designed electromagnetic recuperator can meet the thrust demand of artillery,and the response of the FCS-MPC algorithm is fast,which can re-advance the artillery body quickly and accurately to the position before firing,and it can maintain the artillery body in the position ready to fire at different firing angles.
