| 中文摘要 |
| 研究了使用量化技术解决控制器局域网络(CAN)总线网络控制系统的带宽受限问题. 首先, 建立了多控制回路的网络控制系统模型, 该模型综合考虑了采用对数量化器对采样信号进行量化和Bernoulli随机网络丢包过程. 并针对量化误差和数据丢包, 设计了控制器和观测器使得闭环系统指数均方稳定. 然后根据控制性能最优化要求, 设计了在带宽受限情况下的反馈网络调度器, 提出了量化反馈调度策略. 最后通过对3个独立控制回路组成的CAN总线系统进行仿真实验, 验证了此调度策略的有效性和可行性. |
| 英文摘要 |
| 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. |
