摘要
提出了航空起发一体电机系统控制器的设计方案,采用矢量控制及弱磁扩速控制方式实现电动机起动控制,发电整流模块与起动模块分时共用MOSFET三相全桥主功率电路,采用专用芯片实现同步整流,采用BUCK电路并利用多相交错并联降低输出纹波,控制算法采用3零点3极点(3P3Z)补偿方法进行28V输出稳压控制,实现了航空发动机快速起动、永磁同步电机起动到发电的平稳转换以及28V直流电源输出。仿真研究表明系统的起动时间短、动态过程性能好,28V直流电源输出稳定,并联BUCK电路各支路均流理想,具有一定的工程应用价值。
A design scheme for an integrated motor system controller for aviation starting was proposed,which adopted vector control and weak magnetic field expansion control to achieve motor starting control.The generation rectifier module and starting module share a MOSFET three-phase full bridge main power circuit in time sharing,and a dedicated chip was used to achieve synchronous current regulation.A BUCK circuit was used and multiple intersecting faults were used in parallel to reduce output ripple.The control algorithm adopted a 3-point 3-pole(3P3Z)compensation method for 28V output voltage stabilization control,achieving fast starting of the aircraft engine,smooth conversion from permanent magnet synchronous motor starting to power generation,and 28V DC power output.Simulation studies have shown that the system has short starting time,good dynamic process performance,stable output of 28V DC power supply,and ideal current sharing of all branches of the parallel BUCK circuit,which has certain engineering application value.
