介绍了DCS控制系统在宝浪油田联合站生产运行中存在的问题，重点分析了PID控制回路数字平滑滤波技术、动态补偿技术以及串级控制回路技术，提出了优化系统的方法，并在控制系统中加以改进，对消除温度滞后、提高数据采集速率、改善整个系统的控制性能、提高技制精度起到了明显的作用，并给出了改进后的效果对比图。
The problems of the DCS control system in the production and operation of Baolang Oilfield Joint Station are introduced. The digital smoothing filtering technology, dynamic compensation technology and cascade control loop of PID control loop are analyzed emphatically. The method to optimize the system is put forward. The control system In the improvement, to eliminate temperature lag, improve data collection rate, improve the control performance of the entire system, improve technical accuracy played a significant role, and gives a comparison of the improved results.
