This paper presents the design of a discrete event controller for Marnoch Thermal Energy Conversion (MTEC) system test bed for optimization its performance. The controller has been designed with a simulation of the MTE using MATLAB, Simulink, and Stateflow software. A UML model is developed to analyze inputs and outputs requirements for the controller which drives valves and flow direction between...
Homogeneous charge compression ignition (HCCI) engines create a cleaner and more efficient power source for either stationary power generators or hybrid vehicles. Control of HCCI engine, however, is difficult since its ignition cannot be actuated directly. For the purpose of model-based analysis and controller design, a model for a single cylinder HCCI engine with electric mechanical valves (EMV)...
Three different strategies based on a theoretical model were used to simulate engine start process respectively, start in constant speed without compensation, start in constant speed with compensation, normal start. Predication results are presented here. Bench tests were also carried out, which are related to the three control strategies. It is found that the start in constant speed with compensation,...
According to the design requirements, the powertrain dynamic simulation model of an integrated starter/generator (ISG) hybrid electric vehicle (HEV) was established using Simulink. The parallel electric assist control strategy (PEACS) was researched and designed in this paper. The analysis of dynamics performance and fuel economy of the model was carried out under the FTP drive cycle, which can provide...
