-
摘要: 研究一类带有独立时变输入扰动非线性系统参数估计的多项式逼近方法.在一定的 假设条件下给出了时变输入扰动所引起的输出扰动的形式,并讨论了输出扰动的可预报性. 仿真试验说明了该方法的有效性.Abstract: The approximation method based solution to parameter estimation for nonlinear systems with independent input perturbation is studied. The form and the predicability of output perturbation caused by time-variant independent input perturbation are presented under some hypotheses. Simulation examples demonstrate the effectivence of this method.
