| Abstract: | A method of continuous .time system model identification based on Haar wavelet is presented. By using the operational matrix of integration based on Haar wavelet, the differential equation can be converted into algebraic equation efficiently and simply. Based on the measured data from the system, the model parameters can be identified by the method presented here together with the least square method. A off-line algorithm is Presented and the simu- lation shows its effectiveness. |
