评估和调试太阳能电池板驱动的系统是一个繁琐的过程。该系统必须部署在野外，远程识别软件和硬件错误，并且必须重复开发周期，以构建一个健壮的系统。太阳能电池板的仿真平台提供了一个看似合理的补救措施，然而，现有的系统工作范围较窄，而且不便于携带。为了解决这些不足，我们设计、实施和评估了SunaPlayer，这是一个太阳能电池板仿真平台，支持宽工作电流范围(430微安到1.89安培)和电压范围(0.02 V到9.8 V)，并且可以使用电池供电。SunaPlayer使用高增益模拟器件、PNP达林顿晶体管、多尺度驱动和测量电路以及基于新型状态机的比例-积分-微分控制器来建立太阳能电池板的精确非线性模型。我们已经实现了一个全功能的SunaPlayer原型，并证明了它可以模拟各种高精度、低延迟、高灵敏度和低功耗的太阳能电池板。SunaPlayer的设计方法可以用来构建难以模拟非线性设备的系统。
Evaluating and debugging solar panel-driven systems is a cumbersome process. The system must be deployed in the wild, software and hardware bugs identified remotely, and the development cycle must be repeated to build a robust system. Emulation platforms for solar panels offer a plausible remedy, however, existing systems have narrow operating range and are not portable. To address these shortcomings, we design, implement, and evaluate the SunaPlayer, a solar panel emulation platform that supports a wide operating current range (430 micro-amps to 1.89 amps) and voltage range (0.02 V to 9.8 V), and can be powered using batteries. SunaPlayer uses a high gain analog device, a PNP darlington transistor, a multi-scale driving and measurement circuit, and a novel state machine based proportional-integral-differential controller to build an accurate non-linear model of the solar panel. We have implemented a fully functional SunaPlayer prototype, and demonstrate that it can emulate a wide range of solar panels with high accuracy, low latency, high sensitivity, and low power consumption. The design methodology for the SunaPlayer can be used to build systems that model hard to emulate non-linear devices.
