Description
Summary:博士 === 逢甲大學 === 電機與通訊工程博士學位學程 === 101 === This study performs optimal estimation of circuit parameters for a biohydrogen real-time power generation system by the differential evolution and genetic algorithms, this study attempts to optimize estimation of a biohydrogen real time power generation system in which circuit parameters fluctuate with operating temperature and current density. Based on uses of the differential evolution algorithm method, optimal estimation of the circuit parameters is achieved by data from a V-I characteristic experiment on the proposed biohydrogen real time power generation system. Hydrogen can be by biological fermentation technology from material sources and disposal of non-food biomass production, the process of producing hydrogen can be by real-time monitoring of pH, temperature, strain, pressure disturbance with the hydrogen production rate and other parameters to control the biological production the efficiency of hydrogen reactor. This dissertation design Fuzzy and Fuzzy-PID controller to improve the proposed anaerobic bioreactor system hydrogen production. The results are compared with the past system without Fuzzy or Fuzzy-PID control. The fuzzy control system we designed can not only control the feeding pump and heater operations, but also successfully reduce the energy consumed by hydrogen production, making sure the growth of microorganisms is in the best environmental conditions for the best growth rate and raise of the maximum hydrogen production. The result shows that the monitoring and control system can control the pump and heater in real-time to reduce the energy consuming and achieve the purpose of energy saving. It also makes microorganism grows in proper environment to obtain better hydrogen producing speed and quantity, to reduce the cost of electric power generation and energy consumption.
