In a method for detaching a frozen charge from an inner wall of a grinding tube of a tube mill, a motor of a drive system is operated in a first mode to rotate the grinding tube for grinding. In a second mode, the motor of the drive system is operated to remove the frozen charge from the inner wall of the grinding tube such that operation of the motor to effect a rotational movement of the grinding tube is repeatedly disturbed by a disturbance signal to cause a repeated disturbance within a variable time interval, with the time interval of the repeated disturbance being shortened.

Disclosed is a soft sensing method for difficult-to-measure parameters in complex industrial processes. A linear selection of high-dimensional original features is performed using correlation coefficients, and several linear feature subsets are obtained based on a preset set of linear feature selection coefficients. A nonlinear selection of the original features is performed using mutual information, and several nonlinear feature subsets are obtained based on a preset set of nonlinear feature selection coefficients. Linear and nonlinear submodels are established based on the linear and nonlinear feature subsets, respectively, resulting in 4 submodel subsets including a linear submodel of linear features, a nonlinear submodel of linear features, a linear submodel of nonlinear features and a nonlinear submodel of nonlinear features. A SEN soft sensing model for difficult-to-measure parameters with better generalization performance is obtained by selecting and merging the candidate submodels based on an optimization selection and a weighting algorithm.
