摘要
基于TTCAN协议提出了一种静态调度算法,该调度算法从控制系统稳定性角度出发,在基本周期中引入了"同步相"和"异步相"的概念,有效利用了总线带宽并且避免了非周期信息对周期性信息造成的扰动,最后通过实验验证了算法具有较好的性能.
A static scheduling algorithm is proposed for networked control systems based on TTCAN protocol from the point of the stability of control systems. 'Synchronous Phase' and 'Asynchronous Phase' are introduced in the basic cyclic of TTCAN. The scheduling algorithm utilizes the fieldbus bandwidth effectively and avoids the jitter on the periodic message from the aperiodic message. The experiment results show that the proposed scheduling algorithm has good performances.
