| 中文摘要 |
| 通常高采样速率有助于提高控制系统性能,但采样速率受限于控制器的执行周期.并行计算是缩短控制器执行周期的有效方法之一,网络化控制系统为控制器的并行执行提供了必要的条件.利用流水线思想,通过在现场总线控制系统中集成控制与调度,实现了控制器以流水线的方式并行执行,使得控制系统的采样周期小于控制器的执行时间,从而获得控制系统性能的提高.仿真结果及理论分析证明了这一方法的有效性. |
| 英文摘要 |
| Generally,the higher the sampling rate is,the better the control performance is.But the sampling rate is limited to the period of controller execution.To reduce the period of controller execution,parallelization is proposed.The networked control system enables parallelization of controller execution.Based on idea of pipeline,by integrating the control and scheduling in the fieldbus control system,the controller can run in a pipelined fashion.It makes the sampling period shorter than the execution time of the controller,and then the performance can be improved.The simulation results and theoretical analysis show this method works well. |
