Nonlinear dynamic effects of mould-locking force sensor

as one of the main die-casting machine monitoring sensor

affected the measurement accuracy and measuring range

resulting to be disadvantageous to standard production.In order to solve the problem

least squares support vector machine（SVM） method was adopted to compensate nonlinear dynamic sensor

meanwhile

the algorithm is modified.In addition

numerical simulation was conducted.The results show that the measuring accuracy and measurement range of nonlinear dynamic compensation sensor based on modified least squares support vector machine（SVM） are greatly improved

increasing the production efficiency.
