摘　　要：研究了一种人工心脏用圆筒型永磁直线电机,即模块化磁通切换永磁直线电机。对电机的结构和电磁性能进行了深入研究。建立了数学模型,在此基础上推导出了电机在负载突变和往复运动两种情况下的控制策略。利用场路耦合瞬态联合仿真方法,对电机推进系统的运动性能进行了仿真分析。将仿真结果和理论分析数据进行比较,验证了该控制策略的可行性。A tubular permanent-magnet （PM） motor for AHs, termed as modular flux-switching permanent- magnet linear （MFSPML） motor was investigated. The structure and electromagnetic performance were analyzed. Mathematical model was built to deduce the control strategies in both load sudden change and reciprocating motion. Using the method of coupled field-circuit transient co-simulation, the movement performance of motor propulsion system was analyzed in simulation. The simulated results compared with the theoretical analysis, verified the proposed control strategy was feasibh＇.
