摘要
为克服网络控制系统中时延对系统性能的影响,提出了一种基于嵌入式Linux的广义预测控制器(GPC)的设计方案。该方案构建了以ARM9处理器S3C2440A为核心、运行Linux操作系统的嵌入式控制器平台,并通过Boa Web Server实现使用Browser/Server对控制器进行远程访问和参数调整。同时针对网络延迟采用GPC算法,对控制系统的时延进行软件补偿,以实现对被控对象的实时控制。
In order to overcome the impact of time delay on system performance in networked control systems, a generalized predictive controller (GPC) based on embedded Linux is designed. The project takes S3C2440A ARM9 processor as the core, running Linux operating system platform for embedded controller and using Browser/Server mode to achieve remote access to the controller and to adjust parameters through Boa Web Server. GPC algorithm is applied in the networks to compensate for the time delay of the control syste...
