Modelling and Control of a novel SOFC-IC Engine Hybrid System
نویسندگان
چکیده
A novel configuration of a Solid Oxide Fuel Cell-Internal Combustion (SOFC-IC) engine is presented and a nonlinear dynamic model that captures the transient phenomena of this system is developed. A variable geometry turbocharger and a throttle present at the air inlet is used to regulate the interacting flows in the combined system. A controller is developed to regulate the output to demand specific setpoints which correspond to the required power output of the hybrid vehicle. The controller is derived by means of identified linear models. It consists of a feedback term, an integral term and a feedforward term. An observer is used for the estimation of the system states. The nonlinear system is assessed under closed-loop control with simulations.

In internal combustion engines, only about a third of the total fuel input energy is converted into useful work. If the energy rejected into the cooling system and the exhaust gases could be recovered instead and put into useful work, fuel economy would have been substantially improved. The main aim of this research paper was to evaluate the effects of the hybrid nano-catalyst containing ce...
متن کاملA Genetic-Fuzzy Control Strategy for Parallel Hybrid Electric Vehicle
Hybrid Electric Vehicles (HEVs) are driven by two energy convertors, i.e., an Internal Combustion (IC) engine and an electric machine. To make powertrain of HEV as efficient as possible, proper management of the energy elements is essential. This task is completed by HEV controller, which splits power between the IC engine and Electric Motor (EM). In this paper, a Genetic-Fuzzy control strategy...
