由于可靠性提高、成本降低和维修方便，美国海军决定从径向配电改为直流分区配电供舰艇使用。相应地，新型作战舰艇的建造将用半导体开关DC-DC变换器和DC-AC逆变器取代笨重的变压器。电气控制单元ECU用于控制这些变换器和逆变器。ECU的开发从原型设计开始，工程师用它来测试控制物理系统的实验算法的能力。
本论文研究以DSPACE-DSII02型数字信号处理板作为三相逆变器的ECU原型。DSII02监测三相功率MOSFET桥输出端的电流，进行信号处理并相应地提供MOSFET门控信号。本研究比较了几种不同的算法、时间步长以及由DSP板实现的集成方法。在实验中，逆变器为一个简单的RL负载和一个感应电动机供电。对于感应电动机的闭环控制，速度控制算法为先前测试的逆变器提供指令输入。本文研究表明，DSII02能够快速有效地实现未来美国海军舰船配电系统信号处理与控制单元的原型化设计。
Due to enhanced reliability, reductions incost, and ease of maintenance, the U.S. Navy has decided to shift from radialelectrical distribution to DC zonal distribution for shipboard use.Correspondingly, the construction of newer classes of combatant vessels willreplace bulky transformers with semiconductor switching DC-DC converters andDC-AC inverters. Electrical Control Units, ECUs, control these converters andinverters. Development of an ECU begins with a prototype design, used by theengineer to test the ability of an experimental algorithm to control a physicalsystem. This thesis research examines the use of the DSPACE DSII02 DSP board asa prototype ECU for a three-phase inverter. ~ DSII02 monitored currents at theoutput of a three~phase power MOSFET bridge, performed the signal processing,and accordingly provided the MOSFET gating signals. This research comparedseveral different algorithms, time steps and integration methods implemented bythe DSP board. In the experiments, the inverter powered a simple RL load and aninduction motor. For the closed-loop control of the induction motor, a speedcontrol algorithm provided command inputs to the previously tested inverter.This thesis research demonstrates that the DSII02 can quickly and effectivelyprototype the signal processing and control units of the electrical powerdistribution systems of future U.S. Navy ships.
