Disturbance rejection of time-delay observer
Abstract：In order to overcome the negative effect induced by the persistent and high frequency disturbances to the controlled plant, which is the first order object with time delay, a disturbance observer with time delay was put forward, and in the inverse auspices of the controlled plant, Q filter, lead compensator together with time delay approximator, the controlled plant can be well regulated, which came naturally under frequency domain analysis ; and on account of that, the negative effect attributed by the time delay and the persistent disturbance can be cut sharply; finally, a numerical example was further employed to verify the validity of the suggested scheme.
