Unbalance in magnetically levitated rotor (MLR) can cause undesirable synchronous vibrations and lead to the saturation of the magnetic actuator. Dynamic balancing is an important way to solve these problems. However, the traditional balancing methods, using rotor displacement to estimate a rotor’s unbalance, requiring several trial-runs, are neither(More)
This paper made a comparison study on the forecasting of timber growth ring density with support vector machine (SVM) and radial basis function (RBF) neural network. The objective of this paper is to examine the feasibility of SVM in wood density forecasting by comparing it with a RBF neural network. Wood experiments are carried out to get the data sets.(More)
A CMAC (Cerebellar Model Articulation Controller) network combined with PID (Proportion Integration Differential) control method was proposed in this paper. Aiming at the characteristics such as multivariable, strong coupling, nonlinear and time-varying parameters for the turbine regulating system, an improved mutative scale chaotic optimization algorithm(More)
