Microprocessor-based universal adaptive controllers

For an adaptive controller to be effective in cases where the system dynamics are completely unknown and change with operating conditions, it is desirable that the control action be regulated by a single parameter. Two control algorithms which have this characteristic are presented. One is based on the linear quadratic control theory and the other is based on pole placement technique. The microcomputer implementation of these two control algorithms is presented. For such control algorithms to be successful, the on-line program should be user-interactive so that the user can influence the control action. The interactive features are explained. Experimental results are presented to show the successful operation of the controller.
