變分法的參數(shù)約束估計法

The accuracy of parameter estimation is critical when digitally modeling a ship.A parameter estimation method with constraints was developed,based on the variational method.Performance functions and constraint equations in the variational method are constructed by analyzing inputand output equations of the system.The problem of parameter estimation was transformed into a problem of least squares estimation.The parameter estimation equation was analyzed in order to get an optimized estimation of parameters based on the Lagrange multiplication operator.Simulation results showed that this method is better than the traditional least squares estimation,producing a higher precision when identifying parameters.It has very important practical value in areas of application such as system identification and parameter estimation.
