Control strategy with adaptive quantizer's parameters under digital communication channels

摘要: A stabilizing controller designed without considering quantization may not be effectively implemented for the systems with quantized information due to errors. Hence, an interesting issue is how design quantizer such that desired system performance can still attained by above controller. In this work, a new control strategy on-line updating quantizer's parameter proposed. This scheme ensure controlled attain same dynamic performance, H ∞ disturbance attenuation level, as one signal quantization. practical adjusting rule on proposed state-dependent available both sides of encoder/decoder. Finally, some numerical examples have been provided illustrate present scheme.
