| Abstract: | A robustness index for adaptive control is proposed. The control algorithm is based on pole-zero placemen!. Parameter estimation via weighted least-squares recursive formulas is presented. By using the index, effects of the modelling error on the performance of the adaptive control system are indicated. If the index is less than one, the system is stable. Proper on-line control is obtained. |
