汽轮机调速系统的一种HMRAC方案

The HMRAC for using low order model and been used in the adjust speed system of turbo generator

基于混合误差模型，采用滤波器降阶的方法，设计了一种高阶系统跟踪低阶参考模型的混合模型参考自适应控制（ＨＭＲＡＣ）方案。使用低阶参考模型简化了系统结构。应用ＨＭＲＡＣ，避免了系统因数字化而引起的非最小相位问题及非线性影响，有利于进一步提高系统的鲁棒性。应用到汽轮机调速系统中，验证了方案的有效性。

Basing on hybrid error model and adopting diminution order method by filter, a hybrid model reference adaptive control scheme has been designed for high order system following the low order model. The system structure has been simplified by using low order model. Using the hybrid model reference adaptive control, the problem of non-minimum and the influence of nonlinear were avoided, which were caused by digitizing the system. It has the advantage to the robust of the system and been used in the adjust speed system of turbo generator，the effective has been tested。
