本文开发了一种用于植入式设备的联合电源和热管理方法，以实现三个目标：可持续运行、性能最大化和热安全。通过设计合适的目标函数来保证可持续运行和性能最大化。通过增加限制最高温度的约束来保证运行过程中的热安全。可植入设备的温度由为该设备实施的热模型提供。然后利用模型预测控制理论来解决该问题。通过基于先前发布的平台的模拟研究验证了所提出方法的有效性。该平台是无线供电的光遗传学刺激装置，光学模块温度是该应用的主要关注点。在活动模式下，LED 的最高平均输入功率为 250 mW。仿真结果表明，在满足相同热约束的情况下，所提出的方法可以将运行时间延长 34%。
In this paper, a joint power and thermal management method is developed for implantable devices to achieve three goals: sustainable operation, performance maximization, and thermal safety. The sustainable operation and performance maximization are guaranteed by designing an appropriate objective function. The thermal safety during operation is ensured by adding a constraint that limits the maximum temperature. The temperature of the implantable device is provided by a thermal model implemented for the device. Then the theory of model predictive control is used to solve the problem. The effectiveness of the proposed method is validated through a simulation study that is based on a previously published platform. The platform is a wireless powered optogenetic stimulation device, and the optics module temperature is a major concern for this application. The highest average input power to the LED is 250 mW in the active mode. The results of the simulation indicate that the proposed method can potentially achieve 34% more operation time while satisfying the same thermal constraint.
