摘要
经过十几年的发展,软测量技术无论是在理论研究还是在实际应用中均取得了较大成功,然而至今为止的大部分研究都是针对静态软测量模型.分析了静态软测量模型与动态软测量模型之间的区别和联系,利用冲激响应模型给出了一个基于最小二乘方法的动态软测量建模方法,并在该方法的基础上给出了一种改进.仿真例子验证了该方法及其改进的有效性.
After more than ten years of development, great achievements of soft-sensing technology have been made not only in theory but also in practice. Up until now, however, most research work in the softsensing field have been essentially concentrated on static soft-sensing models. The relations and distinctions between dynamic soft-sensing models and static soft-sensing models are discussed. Using the impulse response model, a dynamic soft-sensing method based on least squares is developed. Some improvements to the method are also presented. A simulation example is given to validate the effectiveness of the method and its improvements.
