基于通信干扰观测器的网络控制系统研究

摘要

The network control system has wide applications. To overcome the problems of bad performance and instability caused by the time delay and confusion of the data packet sequence, a solution is proposed using communication disturbance observer strategy. Taking a network velocity modulation system for an example, the system design and parameters adjustment are introduced. Comprehensive simulation is carried out by Simulink. The results illustrate that this method effectively deals with the time delay, and has strong suitability for delay variation, which guarantees the stability and performance of the system.%网络控制系统有着极其广泛的应用背景.为克服网络控制系统中含有延迟、数据包顺序混乱等问题造成的系统性能降低甚至不稳定,提出了采用通信干扰观测器策略进行解决的方案.以某网络控制调速系统为例,介绍了系统的设计和参数调节方法.在Simulink环境下进行了全面的仿真验证,结果显示改进方法能有效处理网络系统中的延迟问题,且对延迟变化具有很强的适应能力,保证了系统的稳定性和性能.
