  • Patent number: 9157741
    Abstract: A method includes simulating operation of a fiber optic gyroscope during a digital simulation. The simulation includes performing an iterative loop that includes simulating an intensity of light from a fiber coil of the fiber optic gyroscope and simulating operation of one or more control loops within the fiber optic gyroscope using the simulated intensity of the light. The intensity of the light is simulated using a sine/cosine function based on at least one angular rate-related effect injected into the simulation as a Sagnac phase shift. The simulated operation of a first of the one or more control loops attempts to reduce or eliminate the Sagnac phase shift. The method also includes storing, outputting, and/or using results of the simulation. The at least one angular rate-related effect could include rotation of the fiber coil and/or mechanical vibration of the fiber coil.

  • Patent number: 9075939
    Abstract: A method for the co-simulation of two or more interacting mathematical models in which each model has at least one input port and one output port for inputting and outputting values of parameters in a predefined parameter protocol. The unit of measurement is identified for each parameter in the model and a scaling factor is then generated to equalize the units of measurement for each parameter in each model. The parameter protocol for each port is then determined and a virtual bus with unique locations is configured for each parameter in the models. The parameters from the models are then configured as a function of the parameter protocol so that the same parameters from different models are associated with the same location in the virtual bus.
