摘要:調節閥是自控系統中的最終執行原件,一切控制方案的實施都由控制閥執行,因此控制閥回路的組態正確是自控系統正常工作的保證。本文通過對控制回路各個環節的討論,明確了各環節的設置原則和方法,對實際工程項目具有指導意義。
關鍵詞:調節閥;定位器;PID作用方式
Abstract: The control valve is the final execution device in the automatic control system, and the implementations of all control schemes are performed by the control valve. Therefore, the correct configuration of the control valve in a control loop is the guarantee for the normal operation of the automatic control system. Through the discussion of each link in a control loop,this paper clarifies the setting principles and methods of each link which have guiding significance for practical engineering projects.
Key words: Control valve; Positioner; PID control mode
