48 v起动发电机的能量平衡

这个例子显示了一个室内永磁同步电机(IPMSM)作为起动/发电机在一个简化的48 v汽车系统。系统包含一个48 v电力网络和一个12 v电网络。内燃机(ICE)是由基本机械块表示。IPMSM是一个电动机,直到冰到怠速,然后是一个发电机。IPMSM供应48 v的权力网络,其中包含R3电力消费。12 v的48 v网络供电网络有两种消费者:R1和R2。仿真总时间(t)是0.5秒。在t = 0.05秒,冰打开。在t = 0.1秒,R3开关。在t = 0.3秒,R2开关,增加了12 v电力网络负荷。 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.
