Scheduling strategy for logarithmic quantization under bandwidth constraints based on controller area network bus
带宽受限的CAN总线对数量化调度策略

A logarithmic quantization strategy for solving bandwidth constraint problems is discussed. A multi-loop model with logarithmic quantized sampling signals and Bernoullian random packet losses on the network is established. To deal with the quantization error and the packet loss, we develop a controller and an observer for stabilizing the multi-loop system in the exponentially mean-square sense. Moreover, a quantization scheduling strategy under bandwidth constraints is presented to optimize the control performance. Finally, the effectiveness and feasibility of the quantization scheduling strategy are tested and validated through simulations of a controller area network(CAN) bus system with three control loops.
