    • A control system for a door or gate which is movable between an open position and a closed position by an automated operator, comprising a door travel organizer which divides the door travel into a plurality of segments and each segment into a plurality of sectors; a sensor to sense at each sector, the resistance of the door or gate against opening and closing whilst moving between the open position and the closed position over a predetermined number of open close cycles, and to generate at least one signal representative of that resistance in each segment over the open close cycle, a recorder connected to the sensor to receive each representative signal and to store such a signal; a comparator to compare each signal with a resistance trip point set for each segment and generate a resistance profile for the door or gate over an open close cycle of the door or gate; a calculator to calculate the resistance trip point for the door or gate for each segment based upon the highest resistance encountered in any sector of that segment; and a controller to receive each trip point and set each trip point as a threshold for each segment such that if resistance of the door or gate sensed by the sensor in any sector exceeds that threshold for that interval, the movement of the door or gate is interrupted.

    • A valve position controller tuning method avoids impact of friction in valve positioner tuning by building a dynamic model of a valve positioner from a monotonic open-loop response of a valve stem position to a change in valve position controller output. To this end, a model form is selected based on the type of pneumatic actuator and relay that controls valve flow modulating of member motion, and the valve position controller is operated in an open-loop mode. The method includes changing a valve position controller output signal to cause the valve positioner to move a valve flow modulating member, connected to valve positioner, monotonically from one stuck position to another stuck position immediately after a motion in that same direction. When a valve stem position reaches a position threshold, a first valve stem position change and a corresponding time change are measured. The method includes measuring valve stem position changes at times that depend on the first measured time change. Using the measured results, valve positioner response parameters are calculated for the selected model form from which valve position controller tuning constants are calculated.
    • 阀位控制器调节方法通过从阀杆位置的单调开环响应到阀位控制器输出的变化构建阀定位器的动态模型来避免阀定位器调节中的摩擦的影响。 为此,基于控制构件运动的阀流量调节的气动致动器和继电器的类型来选择模型,并且阀位控制器以开环模式操作。 该方法包括改变阀位控制器输出信号,使得阀定位器将与阀定位器相连的阀流量调节元件从一个卡止位置单调移动到紧接在相同方向的运动之后的另一个卡住位置。 当阀杆位置达到位置阈值时,测量第一阀杆位置的变化和对应的时间变化。 该方法包括在取决于第一次测量的时间变化的时候测量阀杆位置变化。 使用测量结果,计算阀门位置控制器调节常数所选择的模型形式的阀门定位器响应参数。
