Real-Time Temperature Drift Compensation Method of a MEMS Accelerometer Based on Deep GRU and Optimized Monarch Butterfly Algorithm

Abstract: In recent years, inertial sensors based on Micro-Electro-Mechanical Systems (MEMS) have become increasingly popular. They have been widely used in various fields due to their low cost, small size, and low power consumption. It seems that MEMS inertial sensors may eventually fully occupy the middle to lower end inertial navigation application market that traditional inertial sensors previously occupied. To realize the full potential of MEMS inertial sensors, one of the critical issues is their temperature drift… Show more

“…Our algorithm achieved a greater reduction in random walking compared to Zhu et al [9] RBF NN + GA + KF method (96.11% reduction versus 95.53% reduction), as well as compared to Guo et al [37] DLSTM, RNN, and ISSA method (without denoising decomposition algorithm) (96.11% reduction versus 57.40% reduction), and Gang et al [38] GRU, RNN, short GRU, and optimized monarch butterfly method (96.11% reduction versus 92.15% reduction). This indicates that our method provides superior accuracy in reducing acceleration random walking.…”

“…Figure 6 shows a comparison of various algorithms in terms of average error. At the beginning iterations (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20), the ARO and HGS algorithms have higher average errors than the others, whereas the proposed iHBAGTO algorithm has the lowest average error. As the number of iterations increases, the average error decreases for all algorithms, but the iHBAGTO algorithm consistently outperforms the others with the lowest average error.…”

“…The minimum hop value between i and j is represented by hi, j. The hop size is the hop size from anchor node i to its neighbors, and it is broadcasted by node i using controlled flooding throughout the network [18]. The value of hu, i represents the number of hops between anchor node i and the unlocalized node u.…”
