Constant Voltage Output in Two-Chamber Microbial Fuel Cell Under Fuzzy PID Control

摘要

Microbial fuel cells (MFCs) have been receiving more and more attention in simultaneous treatment ofwastewater and energy recovery. Past research has been mainly in experiments. Modelling andcontrolling are new subjects emerging recently. A novel dynamic model of MFC based on biochemicalreactions, Butlerolmer expressions and mass/charge balances is proposed with Matlab/Simulink, andthen the fuzzy PID controller is designed for the microbial fuel cell to realize constant voltage output.Simulation results show that the proposed controller can give better control effects compared to PIDcontroller.
