基于实时预测的传感器信号倍频算法
Frequency Multiplying Algorithm for Sensor Signal Based on Real-Time Predicting
摘要
Abstract
The Wearable Power Assist Robot is an autonomous device, which can drive itself according to the force information and the angle information from the sensors,and whose assist effect is closely related to the frequency of the sensor signal. In order to improve the assist effect, we propose an algorithm to multiply the response frequency of the sensor signal. The algorithm firstly gets the predictive signal by using the modified MWQAR predicting algorithm,and then uses cubic spline interpolation method to interpolate the compensation signal between the real signal and the predictive signal. In addition, the algorithm can meet the requirement of the real-time while exponentially improving the sensor signal's response frequency. Finally, some correlative experiments have been conducted and the results verify the feasibility and effectiveness of the proposed algorithm.关键词
