ADAPTIVE MODEL FOLLOWING CONTROL BY USING MINIMUM NORM STATE VECTOR FOR SECOND ORDER SYSTEMS

In this paper,the concept of the MNS vector,i.e.,minimum norm state vector,is defined,and the relation between the state vector of a single-input single-output system and its MNS vector is analysed.And herefrom a new adaptive model following control algorithm utilizing MNS vector is proposed.Compared with the present adaptive algorithms,the on-line computation time of this one is the least.Its good control accuracy and robustness can also be assured.
