摘　　要：给出了具有对称循环结构的组合系统在可调系统参数均时变或未知的情况下模型参考自适应控制的 3个基本条件和一般步骤 ,并保证系统的李亚普诺夫稳定性·充分利用系统的对称循环的结构特点 ,降低Riccati方程的维数 ,大大简化了计算 ,易于工程实现·且可调参数可以是无界的 ,其适应律不依赖于广义误差的导数 ,从而解决了这类具有特殊结构的系统在自适应控制过程中的一些困难·Three basic conditions and general approach of the model reference adaptive control of composite system with symmetric circulant structure were given at the condition that parameter of modified system are all time varying and uncertain. Through making goood use of the characteristic of the symmetric circulant structure of the system,the general approach not only assure the Lyapunov stability of the system,but also reduce the dimension of the Riccati. Therefore,it makes the calculation more easier to be realized in engineering. Moreover the parameter of the modified system can be no bounded and the adaptive law doesn't depend on derivatives of the generalized errors. few difficulties in the process of adaptive control of the high dimension adaptive system were solved.
