电路瞬态过程中响应模型的参数估计
Parameters Estimation of the Response Model in Transient Process Circuit
摘要
Abstract
In order to measure each parameter on the response model, an algorithm on parameters estimation is put forward. It is based on curve-fitting's nonlinear least squares optimization, when the response of electric voltage or current is supplied by discrete data in transient process of circuit. Firstly, the algotithm structure squared residual objective function and offered calculating method on each initial values of parameters, then it searched the minimum value of objective function using Quasi Newton Method. This method can calculate all the parameters in model at a time. So the emulation examples and the simulation results show that it has better stability and higher rapidity of convergence and precision of calculation.关键词
