Abstract Model-based control strategies for microbial fuel cell are able to create a balance between fuel supply, mass, charge and electric charge, performance efficiency. This paper designs a new adaptive sliding mode control scheme of single chamber single population microbial fuel cell. The adaptive method estimates parametric uncertainty and nonlinear terms while the sliding mode method achieves microbial fuel cell performance targets. The significant advantage of the suggested scheme is its capability to provide robustness against parametric uncertainties and handle systems nonlinearity. The Lyapunov technique has been used to demonstrate robust stability in the face of nonlinearity and uncertainty. Numerical simulations confirms that the proposed control method is able to meet the desired specification in the presence of varieties of parametric uncertainty. Keywords Adaptive sliding mode control · Microbial fuel cell · Nonlinearity · Parametric uncertainty
1 Introduction Today, the importance of energy in the life of human societies is not hidden from anyone. Increasing demand for energy has been accepted as a fundamental and vital issue, and we must provide appropriate solutions to meet the needs of different societies. Although the nature of this demand varies between developed and developing countries (one to improve the quality of service and life and the other to meet basic needs), so the growing energy needs must be met in some way. Renewable energy is resultant from natural processes that are replenished constantly and using of it is a reliable way to supply energy to meet the growing energy needs. In various forms, it originates directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity generated from solar, wind, ocean, * Li Fu [email protected] Xiuwei Fu [email protected] Hashem Imani Marrani [email protected] 1

hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources [1–8]. Reducing energy dependence, stable energy prices, increasingly competitive, reliability and resilience, less global warming and improved public health are some benefits of the renewable energy. In recent years, attention to the renewable energy potential of the microbial fuel cell (MFC) has increased for several reasons. Using MFCs is very beneficial to the environment as it helps in the reduction of pollution and cuts the cost of water treatment tremendously. Apart from being an energy source, MFC also has the potential to provide sustaina
