| 中文摘要: |
| 针对时隙ALOHA随机调度下的离散网络控制系统，提出一种闭环系统特征矩阵谱条件数与极点配置相结合的控制器设计方法．为了同时考虑控制系统与通信系统性能，将闭环系统特征矩阵谱条件数的最小值问题转化为无约束最优化问题，进而实现控制器设计的优化，降低控制系统对信道吞吐率的要求，使得控制系统与较低吞吐率的通信系统同时稳定，从而实现网络控制系统的稳定．仿真结果表明，该方法设计的控制器具有良好的控制性能，能够在较低吞吐率的信道中稳定运行． |
| 英文摘要: |
| For the discrete networked control system under slotted-ALOHA scheduling protocol, a controller design method is proposed based on the spectrum condition number of eigenmatrix and pole assignment of the closed system. Considering both of the performances of control system and communication system, the minimization problem of the spectrum condition number of eigenmatrix for the closed system is looked as unconstrained optimization problem to realize the optimization of the controller and reduce the need of channel throughput by control system, which can simultaneously stabilize the control system and the low-throughput communication system, and finally realize the stabilization of the networked control system. The simulation results prove that the controller designed by the method is of good control performance and can guarantee the stability in the channel with low throughput. |
