摘　　要：结合工程实例,分析了串级三冲量与单级三冲量控制系统原理和DCS组态实现,指出了串级三冲量控制系统在工况条件下PID参数整定存在的问题,提出了一种改进型单级三冲量控制系统。生产实践表明:该系统稳定可靠,PID参数整定更加简单快捷,操作方便且控制效果好。Combined with project cases,the working principle of cascade-three parameters and single-stage three-element control system and DCS configuration were analyzed; and matters bothering PID parameter tuning in cascade three-element control system under working conditions were presented to propose an improved single-stage three-element control system. The production practice shows that,the improved single-stage threeelement control system is stable and reliable,and the PID parameters tuning becomes simpler and faster along with easy operation and a good control effect.
