Abstract:Using the sensor array can carry the multi-dimensional measurement. Through integral the line acceleration and velocity of angular can get the position and carriage of the move coordinate system. But this method produces an accumulation of errors by time growth, limited the time of sensor array test. Using the method of EMD get a series of IMFs and separating the error IMFs from the right IMFs can get the correct integral data. This method is effectively proved by simulations and experiments to prove the effectiveness of the method.
