Abstract: A method to control a fluid flow regulating device being regulated through a control signal ranging from 0-100% during a normal operational load, defined as being within a given load threshold, where said control signal is 0% when said flow regulating device is to be closed and 100% when it is to be open, but when said load gets outside said load threshold the control enters a modified control where said control signal either is never at 0% and/or is never at 100%. A controller including said control method.
Abstract translation: 控制流体流量调节装置的方法通过在正常操作负载期间范围从0-100％的控制信号来调节，该控制信号被定义为在给定的负载阈值内，其中当所述流量调节装置要求时，所述控制信号为0％ 当它打开时关闭和100％，但是当所述负载超出所述负载阈值时，控制器进入修改的控制，其中所述控制信号从未处于0％和/或从未处于100％。 包括所述控制方法的控制器。
