There is an increasing interest in studying quantized control systems with multiple sensors and actuators distributed for wired and wireless networks. In this paper, we formulate a real-time scheduling problem with bandwidth constraints from quantization control perspective and develop a quantization real-time scheduling scheme for networked and quantized control systems of multi-tasks linear dynamical systems with constrained bandwidth. Our aims include not only designing the encoder/decoder pairs and quantization real-time scheduling scheme required to satisfy some control performance, but also discussing the scheduling scheme's effect on bits total numbers from the quantization perspective. The simulation shows the quantized real-time scheduling scheme is effective and useful.
