Optimization method for the layout of IMUs in deformation detection system of warship based on genetic algorithm
The deformation of warship will influence the accuracy of angular position about the equipment in the deck. IMUs(Inertial Measurement Unit, laser gyros and accelerometers) are installed on various points of the warship to estimate the deformations. Genetic algorithm is utilized for the optimization of the layout of the IMUs, the fitness function of the genetic algorithm is built by the ship's Modal Assurance Criterion (MAC) matrix. Results show that the Genetic algorithm based method presented in this paper can give an optimal layout of the IMUs for detecting the deformation of the warship.
Use of ring laser units for measurement of moving object deformations
The analysis of the method for the ship deformation measurement is submitted. This method is based on the installing of the ring laser blocks in various points of the object. Kalman filter estimates the static and dynamic deformations by processing the output signals of these units. To make the mathematical model of the method more precise, influence of the gyro drifts was taken into account. Investigations of the filter sensitivity to accuracy of deformation model are carried out. The results of investigations of the filtering efficiency in various condition of the ship rocking are given.
