阶、时滞及系数都未知的系统的辨识和适应控制

IDENTIFICATION AND ADAPTIVE CONTROL FOR SYSTEMS WITH UNKNOWN ORDERS,TIME-DELAY AND COEFFICIENTS

假设对一个客观的物理系统我们一无所知,唯一可以获得的信息是给了系统的输入后可以量测到系统的输出、对这种“一无所知”的系统的辨识和适应控制并不是容易的事情,下面我们假定客观的系统是由随机差分方程描述的,即输入、输出和噪声之间的关系如下:

The recursive estimates for the system orders,time-delay and coefficients are given in thispaper.The adaptive control optimizing the performance index and making parameter estimatesconsistent is designed for systems with unknown orders,Further,the convergence rates of coef-ficient estimates to their true values and of the performance values to the minimum are also de-rived.
