The technical level of winding a fiber optic sensor coil during which the tension control is a particularly critical part has a direct impact on the performance of the FOG. The system of tension control on the fiber based on the principle of bond graph during winding is described, and the state-space equation by analyzing the whole process of bond graph is derived. The simulations performed using the Matlab software and the output of the test result for this system verify the validity of the model and provide theoretical basis and advanced control algorithm for practical engineering application in the next step.
