In order to improve the control performance, a so-called lumped disturbanceis considered in the polynomial fuzzy model. As a result, two fuzzy controllers are proposed, in which one involves a disturbance observer. Though both controllers are able to stabilize the control system, computer simulations conclude that the performance by the one with the… (More)
To decrease the quantization noise, various 1-bit digital filters are shown. In this paper, we propose a design method of 1-bit digital filter using a new 2-Degree-of-Freedom control. This design method is applied to a high-pass filter, a low-pass filter and a equalizer. These filters are implemented on DSP, and the performance is verified by the experiment.
