摘要
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.
It is essential for building precise nonlinear control system to exactly and fast identify state and parameter ofnonlinear dynamic system simultaneously.In this paper some mistakes in reference[1] are pointed out, and an im-proved nonlinear filter is proposed.It can be used to identify the state and parameter of the system simultaneously.The effectiveness of the filter is proved by computer simulation.
