针对工业过程中某些重要过程变量难以实现在线检测的问题,提出了一种基于小波和最小二乘支持向量机(LSSVM)的软测量建模方法.首先通过小波变换把样本数据序列分解为不同频段的子序列,然后对这些子序列分别采用LSSVM进行建模,最后通过小波重构得到主导变量的估计值.其中采用量子粒子群算法(PSO)来优化选取LSSVM参数.通过仿真实验验证此方法,实验结果表明所提出的方法具有估计精度高、泛化能力强等优点.

Some industrial process variables are very difficult to measure. To overcome this problem, a soft sensor modeling, based on wavelets and a least square support vector machine (LSSVM), was proposed. Initially, a stream of sample data was decomposed into subsequences with different frequences. This was done on the basis of wavelet transform. Then the respective subsequences were modeled by appropriate SVMs. Finally, estimated values for the primary variables were obtained by wavelet reconstruction. A quantum particle swarm optimization (QPSO) algorithm was employed to select parameters for the LSSVM and the kernel function. Simulation results confirmed that the proposed method has high precision and good generalization ability.
