Abstract The presented two-input two-output fourth-order integrated (TITO-FOI) DC–DC converter is capable of regulating DC-bus voltage and low voltage source current with only two switches and four energy storage elements. Each switch duty control signal in TITO-FOI converter system will affect the two output variables causing interactions. These interactions must be measured for proper controller structure selection. Interactions measurements may not be accurate for a converter system as some methods suggest centralized and some other suggest decentralized control schemes. Hence, there is an ambiguity in selection of suitable controller architectures. To overcome such an ambiguity a centralized interaction independent controller was designed for TITO-FOI DC–DC converter using loop-shaping design procedure. The effectiveness of TITO-FOI converter along with this centralized controller for the regulation of load division and bus voltage is demonstrated with simulation studies using a 36 V/12 V to 24 V, 100 W, prototype DC power distribution system.

用于二输入二输出四阶 DC-DC 转换器的稳健多变量控制器设计

摘要 所提出的二输入二输出四阶集成 (TITO-FOI) DC-DC 转换器能够仅用两个开关和四个储能元件来调节直流母线电压和低压电源电流。TITO-FOI 转换器系统中的每个开关占空比控制信号都会影响导致相互作用的两个输出变量。为了选择合适的控制器结构，必须测量这些相互作用。对于转换器系统，交互测量可能不准确，因为一些方法建议集中控制，而另一些方法建议分散控制方案。因此，在选择合适的控制器架构方面存在歧义。为了克服这种模糊性，使用环路整形设计程序为 TITO-FOI DC-DC 转换器设计了一个集中式交互独立控制器。
