中文摘要
      利用输出误差向量组成一正定二次型目标函数,然后应用各种梯度法计算待估的参数。为改进迭代计算的收敛特性,文中建议增加输出误差向量的维数。本方法的主要优点在于利用系统输入输出的有限数据即可求得参数真值。文中还说明本方法也可用于模型参考自适应控制系统的设计。
英文摘要
      A positive definite quadratic cost function is formed by using the vector output error and then different gradient methods are applied to calculate the parameters to be estimated. In order to improve the convergence property of the iteration the augmentation of the dimension of the output error vector is suggested. One of the important advantages of the proposed method is that the true parameters can be obtained by using limited sampling data of the system input and output. It is shown that the proposed design method can also be applied to determine the controller parameters for model reference adaptive control systems.
