Abstract: |
The sampling period is decided sampling control system stability and related control performance of one of the important parameters, but the sampling period of no fixed mode selection, this paper, based on PLC electro-hydraulic position servo control system by way of comparing, analyzing and determine the sampling period of system. First, based on the Siemens S7-200 PLC, design electro-hydraulic position servo loop PID control system, Secondly, through the experiments of different sampling cycle control performance, Finally, the experimental results, such a rational range of sampling system.
