چکیده
|
This paper presents an application of the design of experiment(doe) techniques to determine the optimized parameters of the artificial neural network (ann)model, which are used to estimate the force from the electromyogram (semg) signals. the accuracy of the ann model is highly dependent on the network parameter settings. there are plenty of algorithms that are used to obtain the optimal ann settings. however, to the best of our knowledge, no regression analysis has yet been used to model the effect of each parameter as well as presenting the percent contribution and significance level of the ann parameters for force estimation. in this paper, the semg experimental data is collected, and the ann parameters are regulated based on an orthogonal array design table to train the ann model. the taguchi method helps us to find the optimal parameters settings. the analysis of variance (anova) technique is then used to obtain the significance level as well as the contribution percentage of each parameter in order to optimize ann’ modeling in the human force estimation. the results obtained indicate that doe is a promising solution to estimate the human force from the semg signals.
