PURPOSE:To enable the quantity of state (speed) to be adequately estimated, by estimating the detected value of speed in addition to the actual value of speed. CONSTITUTION:On a motor control system including the delay of the detected value of speed against the actual value of speed by using a pulse generator for a speed-detecting system, the timing and quantitative relation between the actual value omega of speed and the detected value omegad of speed is expressed in terms of figure model. To the model, a state equation for stating a state natural in system is added, and with the equation for a renewed state equation on the whole system, a state observation device is organized. Accordingly, also on a motor control system including the delay taud of the detected value omegad of speed, matching property between the detected value omegad of speed evaluating an estimated error on driving the state observation device, and an estimated value can be obtained. |
