A low-order adaptive controller for a class of minimum-phase system

For the high-order system with uncertain parameters, traditional adaptive approaches tend to obtain high-order controllers and identify many parameters. This paper proposes a low-order adaptive controller for the high-order, minimum-phase system with uncertain parameters, which fully take the advantage of the minimum-phase system, so as to greatly reduce the structure of the controller and numbers of parameters to be identified. The last simulation validates its effectiveness.
