| 摘要: |
| 基于网络QoS如延迟、丢包建立网络化控制系统状态方程,提出一种根据网络QoS离散化连续系统二次型代价函数及设计相应最优LQR(Linear Quadratic Regulator)控制器的方法。针对系统控制性能对网络QoS的约束,提出一种能够兼顾系统性能与网络QoS的控制与调度综合协调设计方法。仿真实验证明了提出的网络化控制离散二次型最优综合设计方法的必要性和与已有的二次型最优控制方法相比的优势。 |

| Abstract: |
| Sections 1 through 3 of the full paper explain the integrated design method mentioned in the title, whichwe believe is new and more effective than previous ones. Their core consists of: (1) we discretize the continuouscontrol model with the network qualities of service (QoS) such as network-induced delay and packet dropout; (2)we discretize the continuous quadratic cost function, which takes network QoS into account, and then design a dis-crete linear quadratic regulator; (3) we propose an integrated design method for scheduling the bandwidth of net-worked control system, which considers both the quality of performance and the QoS. Section 4 simulates our inte-grated design method; the simulation results, given in Figs. 1 through 5 and Tables 1 and 2, and their analysisshow preliminarily that the integrated design method is indeed more effective than previous ones. |
