精确快速地同时估计出非线性动态系统的状态及参数对高精度非线性控制系统是必需的.本文在指出文献[1]若干错误的基础上,给出了一种改进型非线性滤波器,可同时精确估计出系统状态及参数.仿真实例证实了本文方法的有效性.
To accurately and quickly estimate the states and parameters of nonlinear dynamic systems is necessary for high-precision nonlinear control systems.This paper presents an improved nonlinear filter based on some errors in [1] The system states and parameters can be accurately estimated at the same time.The simulation example proves the effectiveness of the proposed method.
