| Abstract: | Applied support vector machine to the compensation of MEMS gyroscope random drift to overcome the disadvantages of traditional methods. The support vector machine prediction model is established firstly, in order to train and test the model, then embedding the scalar gyroscope random drift time series to an assistant phase space by the technology of phase construction. Get the best parameters of core function and prediction model by using the optimization algorithm. Both the train and test results show that this method can predict the gyroscope random drift well; it is an effective compensation method to MEMS gyroscope random drift. |
