MOTOR-AND-CIRCUIT INTERMINGLED SIMULATION METHOD

摘要

PURPOSE:To easily grasp the fine behavior of a system and to prevent an increase in the simulation time of a method by a method wherein a motor is described by a transfer function and a motor-control circuit is described by a circuit model. CONSTITUTION:When a motor designer inputs the circuit model of a motor control circuit 1 to a circuit-and-motor intermingled simulator 12, the level of a model is separated by a function and circuit separation means 16 which separates the content of a file into a function model and a circuit level via a link means 15 in which a function-and-circuit intermingled and modeled motor 14 and the input motor-control circuit have been collected in the same file. Data is analyzed by an analysis means 17. When it is analyzed, various integration methods such as a forward integration method and a backward integration method are selected according to the level of the model by a time control means 18, and the data which has been analyzed is converted into data which outputs a waveform by a waveform output means 19. As a result, the simulation time and the accuracy of the title method can be controlled arbitrarily.
