In a single-cylinder gasoline engine for the study, made a simulation optimization method of engine valve timing. After the construction of a simulation model of the engine, the simulation results are compared with the data of engine bench test to verify the accuracy of the constructed model. For improving the engine power performance, valve timing optimization simulation to this model is carried...
Recently progress in sensor technology, data processing and integrated techniques has made the development of unmanned aerial vehicles (UAV) fully possible. The Eight-Rotor is a radio-controlled vehicle. It is powered by eight rotors and is capable of motion in air in six degrees of freedom. In this paper, we present the dynamic modeling of Eight-Rotor UAV from which we also developed a flight control...
This paper presents an open-architecture Computerized Numerical Control (CNC) system based on Windows CE, which is a multi-task embedded real-time operating system. The CNC system adopts a master-slave architecture, And the Master applies with Windows CE, which charges weak real-time tasks such as NC code's editor, interpreter and simulator function block, fault diagnosis, I/O monitoring and control...
The paper presents control and scheduling co-design of the multitask schedulability for embedded control system by designing and simulating the hydraulic embedded control system (HECS),which is always neglected during the design and may result in unpredictable behaviors. Based on analyzing the function and performance requirements of the HECS, the effect of real-time system choice and control task...
