Unilateral Control Structure Under Communication Rate Constraint

This study proposes a design method of unilateral control systems under communication rate constraints. In case that it is required to control under a communication rate constraint, the input signal should be minimized in the meaning of the data rate by signal quantization. Feedback-type dynamic quantizers are effective for signal quantization. A design method of the dynamic quantizer under communication rate constraints has been proposed by our previous research. A unilateral control structure is proposed for minimizing the effect of the quantization error in this paper. The design method of the quantizer is applied for the proposed structure. Effectiveness of the proposed system with the designed quantizer is assessed through numerical examples.
