| Summary: | 碩士 === 正修科技大學 === 機電工程研究所 === 96 === This thesis is aimed to study the computer simulations and the circuit experiments for the algorithms of the voltage regulators (VR) used in vehicle alternators. The mathematical model of the generator system is developed by MATLAB/Simulink. By the computer simulation, it is very convenient to evaluate different algorithms. After computer simulation, the algorithms are implemented by microcontroller written by the assembler language. The results of the experiments of VR simulation and alternator life testing machine are consistent with that of computer simulation. Both of them, computer simulation and experiment, verify the effectiveness of the proposed algorithm in this thesis. In addition, a Serial Communication Interface (SCI) is reserved for the communications with PCM (Powertrain Control Module) or ECM (Electronic Control Module) of vehicles for the trend of the computerized of vehicle.
