摘要
双余度机电作动伺服系统作为多电及全电飞机伺服作动系统具有体积小、功率密度大优点,提高了飞机伺服系统工作的可靠性。而双余度永磁无刷电机作为此系统中实现电能到机械能转换的关键部件,直接影响系统的性能。通过研究双余度永磁无刷电机组成结构形式及脉宽调制逆变器的开关函数和系统的状态方程,分析双余度永磁无刷电机的互感耦合数学模型,建立双余度永磁无刷电机系统的数字仿真模型,此模型适用于处理该系统所组成的时变网络模型;在对系统特性进行分析的基础上完成了在Matlab环境下的系统仿真,对比分析了系统仿真与试验的波形。结果表明系统建模方法与实际运行结果相近,可以更好地分析余度电机的特性。
Dual-redundancy electromechanical servo actuation system used in the more electric aircraft servo actuation system has the advantages of both small size and high power density,and improves aircraft servo control system working reliability.Dual-redundancy permanent magnet brushless motor（DRPMBLM） used to realize electric energy to mechanical energy conversion is the key component,which directly affects the performance of the system.In this paper,The system topology is proposed by the analysis of the redundancy structure of DRPMBLM.The mathmatical models of pulse width modulation（PWM） converter model and state equations for DRPMBLM system were proposed.In these models,the mutual coupling for the mutual inductances between phases in each redundancy was considered.The simulation adapted to time-varying network model.By using this system model,the dynamic performance and characteristics for the DRPMBLM system were predicted and analyzed.Simulation and experimental results are compared in DRPMBLM system to verify the proposed modeling and characteristics analysis.
