摘　　要：针对子系统间存在参数耦合的多变量系统,利用耦合辨识概念,研究和提出了部分耦合随机梯度辨识方法和部分耦合多新息随机梯度辨识方法,部分耦合递推梯度辨识方法和部分耦合多新息递推梯度辨识方法,部分耦合递推最小二乘辨识方法和部分耦合多新息递推最小二乘梯度辨识方法,以及部分耦合递阶最小二乘辨识方法和部分耦合多新息递阶最小二乘梯度辨识方法。这些部分耦合递推参数辨识方法可以推广到其他有色噪声干扰下的线性和非线性多变量随机系统中。For the multivariable systems that exist the parameter coupling between their subsys-tems,this paper investigates and proposes parameter identification methods for partiallycoupled parameter vector systems based on the coupling identification concept,including partially-coupled stochastic gradient identification methods and partially-coupled multiinnovation stochastic gradient identification methods,partially-coupled recursive gradient iden-tification methods and partially-coupled multi-innovation recursive gradient identification methods,and partially-coupled hierarchical least squares identification methods and partiallycoupled hierarchical multi-innovation least squares identification methods as well.These partially-coupled recursive parameter identification methods can be extended to other linear and nonlinear multivariable stochastic systems under colored noise disturbances.
