Research on Temperature Compensation System of Magnetostrictive Liquid Level Sensor Based on Improved ANFIS
摘要
Abstract
Taking into account the temperature drift of the magnetostrictive liquid level sensor is serious in the large temperature difference,and it is difficult to use the mathematical model to express the nonlinear relation between temperature drift phenomenon and the variety of factors,establish a temperature compensation system based on im-proved ANFIS. This system uses the Additional momentum method to constantly modify premise parameters in AN-FIS in order to avoid the shortcomings that it easy to fall into local minimum point and slow training speed when u-sing the gradient descent algorithm,and improve the capacity of ignoring tiny changes in the network. In order to verify the performance of the temperature compensation system,it has been compared with other temperature com-pensation system based on PSO-LSSVM and BP neural network. Analysis and experimental results show that the maximum error and its mean error of improved ANFIS model is 0.88% and 0.65%,far less than the other two kinds of compensation methods. This temperature compensation system based on improved ANFIS has strong generalization ability and can effectively eliminate the influence by temperature on the magnetostrictive liquid level sensor.关键词
