IDENTIFICATION AND DAHLIN'S CONTROL FOR NONLINEAR DISCRETE TIME OUTPUT FEEDBACK SYSTEMS

Narayanasamy Selvaganesan - Subramanian Renganathan

   An improved identification and control for discrete time nonlinear system is presented in this paper. This design approach contains two phases i) Parameter identification phase ii) Control phase. Once this identification phase is over, the acquired parameter information can be used to implement any control algorithm. In this paper, Dahlin's control algorithm is used for control, as it is more natural than the existing deadbeat control and a new input selection procedure is also evolved to make the scheme attractive.
