| Popis: | An extended Kalman filter and a discrete time adaptive linear quadratic regulator for uninterruptible power supplies are presented. On the control strategy design, the gains are determined by minimizing a cost function which reduces the tracking error and the control signal. An extended Kalman filter identifies and estimates the plant parameters and the unmeasured state variables respectively at different load conditions. |
