最近的微生物燃料电池（MFC）的研究经常解决与规模和可部署性相关的问题。通常需要模块化来减少体积增加时的欧姆损耗。串联/并联通常是一种明显的策略，以提高运行期间的电能质量，最大限度地利用所产生的电力。因此，由电池之间的功率和电压失配导致的电压反转实际上变得不可避免。控制MFC电压可用于稳定MFC堆。在这里，非线性MFC的控制使用简单的增益调度比例+积分的行动。在MFC阵列中实施可能需要节俭控制，从而使成本最小化。控制器参数化使用几个线性模型的MFC的动态工作范围。然后根据运行条件调度控制器增益。数字电位计用于驱动控制，改变来自MFC的电流。结果表明，控制器能够控制MFC电压，抑制干扰。结果表明，该控制器可在不同功率性能的MFC之间转换。这项研究表明，MFC的控制可以实现相对简单的数字方法，可实现使用低成本的微控制器，并可能是有用的MFC在大规模阵列的有效部署。
Recent microbial fuel cell (MFC) research frequently addresses matters associated with scale and deployability. Modularisation is often needed to reduce ohmic losses with increasing volume. Series/parallel is then often an obvious strategy to enhance power quality during operation, to make best use of generated electricity. Hence, voltage reversal resulting from power and voltage mismatch between cells become virtually unavoidable. Control MFC voltages could be used to stabilise MFC stacks. Here, nonlinear MFCs are controlled using simple gain scheduled Proportional + Integral actions. Parsimonious control may be necessary for implementation in MFC arrays, so minimising costs. Controller parameterisation used several linearised models over the dynamic operating range of the MFCs. Controller gains were then scheduled according to the operating conditions. A digital potentiometer was used to actuate the control, varying the current sourced from the MFC. The results show that the controller was able to control MFC voltages, rejecting the disturbances. It was shown that the controller was transferable between MFCs with different power performances. This study demonstrates that the control of MFCs can be achieved with relatively simple digital approaches, plausibly implementable using low cost microcontrollers, and likely to be useful in the effective deployment of MFCs in large scale arrays.
