A Sensor Dynamic Measurement Error Prediction Model Based on NAPSO-SVM

Abstract: Dynamic measurement error correction is an effective way to improve sensor precision. Dynamic measurement error prediction is an important part of error correction, and support vector machine (SVM) is often used for predicting the dynamic measurement errors of sensors. Traditionally, the SVM parameters were always set manually, which cannot ensure the model’s performance. In this paper, a SVM method based on an improved particle swarm optimization (NAPSO) is proposed to predict the dynamic measurement errors o… Show more

“…Moreover, the SVM can theoretically obtain the global optimal solution and can achieve higher accuracy with few samples for the training. In order to improve the prediction accuracy, in it intended to apply the particle swarm optimization (PSO) algorithm in the SVM model to optimize the parameters [17], [18]. In order to resolve the problem of low generalization capacity in predicting the vibration environment of the aircraft platform, Zhang et al [19] combined the PSO and SVM algorithm to propose a novel predicting model.…”

“…However, to overcome the shortcomings of the traditional PSO algorithm, such as slow convergence and the likelihood of falling into a local minimum, its performance was improved by reducing the speed and search range. These modifications were similar to those described for the restricted range PSO algorithm in [22], [23], [28], [31], [32]. In the following, the improved PSO algorithm is referred to as the IPSO algorithm and is used for the optimal selection of SVM learning parameters.…”

“…Although SVM has superior ability in pattern recognition, its performance is affected by parameters. In view of this, various optimization algorithms are developed and applied to search the best parameters, such as genetic algorithm (GA) [22], particle swarm optimization (PSO) [23], sine cosine algorithm (SCA) [24], and grey wolf optimizer (GWO) [25]. As novel optimization algorithms, SCA and GWO proposed by Mirjalili et al have proved effective in many previous works [26][27][28].…”
