In the first report, we described the state estimation observer in the frequency domain. In this paper, a disturbance estimation observer is newly proposed also based on the frequency domain and the structure condition for its design is derived through error analysis. This disturbance observer can be directly and easily constructed from the plant transfer function by applying a diophantine equation with estimation error dynamics depending on input/output disturbance frequency characteristics. The proposed method is applicable to estimate not only input disturbances but also output disturbances. Further, it can also deal with a sinusoidal disturbance. A design example is presented in which the new approach has a good estimation performance for various types of disturbances.
