Integral Backstepping Control of Two Compartment Microbial Fuel Cell

Abstract

Microbial fuel cells (MFCs) are a promising alternative to generate electricity from wastewater. MFCs need an efficient control system to get the optimal output voltage. The present study proposes an integral backstepping controller for the two-compartment microbial fuel cell. The complex higher-order transfer function of MFC is reduced using the approximation method. The effectiveness of the proposed controller is validated in MATLAB/Simulink simulation environment. The performance of the proposed controller is compared with the classical PID controller. The proposed controller's performance outweighs the PID controller.
