N2 - Data quantization is required to design motion control systems with narrow bandwidth. However, performance and stability is significantly deteriorated when control signals in feedback loop is quantized. Therefore, in this paper, optimal dynamic quantizer is utilized to compensate a quantized control signal of disturbance observer based acceleration control systems. Analytical results and experimental results of a position control through a network confirm the validity of the proposed approach. These results show that proposed approach reduces unignorable steady-state errors.
