Research On Automatic Voltage Regulator And Digital Speed-Control System Of Double Salient Brushless DC Motor

First, this paper outlines the structure, the basic operation principle, static characteristic and mathematic model of the novel Double Salient Electro-Magnetic motor. With the help of MATLAB, the paper set up the dynamic simulative model of the high voltage DC generating system based on the generator. Some examples are simulated on this model.Second, this paper introduces the design of hardware of the automatic voltage regulator of the generating system. The frequency-domain model of the voltage regulation system is established. Simulation and analyses on the model are done. The paper gives detailed analyses of the motor's exciting current by the experiment of the voltage regulation system for the first time. The methods of improving automatic voltage regulator are presented based on the analyses of results.Finally, the paper gives a detailed hardware and software design of the digital speed-control system based on 80C196KB. The processes and methods of the whole speed-control system' s experiment are summarized. Angle-advance control mode of the novel motor and parameter regulation of digital PI control are analyzed in details.
