特征模型自适应控制器的参数优化设计

Control Method and Its Applications
Abstract：This paper presents an all-coefficient adaptive control method based on a characteristic model. This method consists of three parts: all-coefficient adaptive control, golden-section adaptive control, and characteristic modeling. It is applied to more than 400 systems of nine kinds of engineering plants. Two such practical examples are introduced in detail to illustrate the concrete steps to apply this method to practical engineering problems. This method has many advantages. It is simple to use, convenient to adjust and test, and able to generate highly robust systems. In certain sense,the method has solved the three principal problems in practical applications, i.e., it can guarantee the stability of a closed-loop system in the start period of a transient process or when parameter estimates have not converged to their “true values,” the number of parameters to be estimated is small ,and the number of parameters to be regulated online is also small. 源自六"维~论`文}网"加7位QQ3249.114 www.lwfree.cn
