Abstract:

In order to solve the problem of very expensive and complicated measurement system currently used,this paper first analysed the factors which affect the speed and torque of the AC asynchronous electrical dynamometer,then put forward a soft-sensing modal based on the support vector regression,which can be used to approximate nonlinear function in the whole region.The experiments prove that the proposed model is effective,and it affords a new method for the measurement of the input power,output power and the torque in the power-mechanical field.

Key words: soft-sensing;the support vector regression(SVR), the AC asynchronous electrical dynamometer;power testing
