48V起动发电机的能量平衡

这个例子展示了一个内置永磁同步电机(IPMSM)在一个简化的48V汽车系统中用作起动器/发电机。该系统包括48V电网和12V电网。内燃机(ICE)用基本的机械块表示。IPMSM作为一个电机运行，直到ICE达到怠速，然后它作为一个发电机运行。IPMSM为48V网络供电，其中包含R3电源消费者。48V网络为12V网络供电，12V网络有两个用户:R1和R2。总的模拟时间(t)为0.5秒。在t = 0.05秒时，ICE打开。在t = 0.1秒时，R3开关打开。在t = 0.3秒时，R2接通并增加12V电网的负载。 The EM Controller subsystem includes a multi-rate PI-based cascade control structure which has an outer voltage-control loop and two inner current-control loops. The task scheduling in the Control subsystem is implemented as a Stateflow® state machine. The DCDC Controller subsystem implements a simple PI controller for the DC-DC Buck converter, which feeds the 12V network. The Scopes subsystem contains scopes that allow you to see the simulation results.
