| Abstract | This paper proposes a method to improve the steady-state accuracy of time-delayed control systems with a communication disturbance observer (CDOB) by low-frequency model error feedback. The advantageous feature of time delay compensation by the CDOB is that it can be utilized without a delay time model. However, the CDOB needs a model of controlled system, and the model error causes steady-state error. To solve this problem, this paper proposes model error feedback only in the low-frequency area. The characteristic of the time delay element e−T s in the frequency domain is described as follows; |
