摘要
从网络控制系统的实际应用出发,在不附加网络同步时钟和对时延特征的离线假设下,运用通讯技术中的网络协议对网络时延进行在线估计;在此基础上,运用最优控制为网络控制系统设计控制器。通过基于CAN总线的实验系统所得结果验证了上述设计的有效性。
An online delay-evaluation approach, namely average delay window(ADW) is introduced for networked control systems, which can characterize the time delays without any synchronized clock in the network and prior assumptions about time delays. Integrated with ADW approach, an optimal control scheme is designed to achieve desired performance despite the uncertain delays in the system. The experimental results based on CAN bus illustrate the effectiveness of the proposed control design and satisfactory performance of the closed-loop system.
