低阶模型的HMRAC方案及应用

The HMRAC scheme with a low order model and its application

采用滤波器降价的方法 ,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。

By adopting a diminution order method with a filter,a hybrid model reference adaptive control scheme has been designed for a high order system following a low order model.The system structure has been simplified by using the low order model.The use of the HMRAC scheme can avoid the problems of a non minimum phase and the nonlinear influence,which are caused by digitizing the system,thus improving the robustness of the system.
