    Abstract translation: 过程控制器（100）基于测量的过程变量（y（t））和设定点（Y> SET <）来控制积分型过程（112）。 过程控制器（100）包括误差产生电路（102），非积分控制电路（104）和自适应偏置电路（108）。 误差产生电路（102）基于设定点（Y> SET <）和测量过程变量（y（t））之间的差异产生误差信号（e（t））。 控制电路（104）产生作为误差信号（e（t））的函数的控制信号（u（t））。 自适应偏置电路（108）向控制信号（u（t）），测量过程变量（y（t））或设定点（Y> SET <）添加偏置值。 作为误差信号（e（t））的函数选择性地更新偏置值，以迫使误差信号（e（t））朝向零。

    Abstract: A process control system (100) controls a non-self regulating process through a control output signal (u(t)) based on a set point YSET and a measured process variable (y(t)). The process control system includes a control circuit (102, 104, 106, 108) having a set point input, a process variable input and a control output. The control circuit generates the control output signal (u(t)) on the control output as a function of the set point YSET received on the set point input and the measured process variable (y(t)) received on the process variable input. An auto-tuning circuit (106) excites the process, estimates a process model based on an intersection between rising and falling asymptotes of the measured process variable (y(t)), and then tunes the control function to the process (110) based on the process model. The auto-tuning circuit obtains robust results, but is computationally simple such that the circuit can be implemented with hardware or software in low-power and low-memory applications, such as in field-mounted controllers.

    Abstract: A process control system (100) controls a process (110) through a control output signal (u(t)) based on a set point (YSET) and a measured process variable (y(t)). The process control system (100) includes a control circuit having a set point input, a process variable input and a control output. The control circuit generates the control output signal (u(t)) on the control output as a function of the set point (YSET) received on the set point input and the measured process variable (y(t)) received on the process variable input. An auto-tuning circuit (106) excites the process (110), estimates a process model based on a rising dead time, a rising rate-of-change, a falling dead time and a falling rate-of-change in the measured process variable (y(t)) and then tunes the control function to the process (110) based on the process model. The auto-tuning circuit (106) obtains robust results, but is computationally simple such that the circuit can be implemented with hardware or software in low-power and low-memory applications, such as in field-mounted control units.

    Abstract: A process controller (100) controls an integrating-type process (112) based on a measured process variable (y(t)) and a set point (YSET). The process controller (100) includes an error generating circuit (102), a non-integrating control circuit (104) and an adaptive bias circuit (108). The error generating circuit (102) generates an error signal (e(t)) based on a difference between the set point (YSET) and the measured process variable (y(t)). The control circuit (104) generates a control signal (u(t)) as a function of the error signal (e(t)). The adaptive bias circuit (108) adds a bias value to the control signal (u(t)), the measured process variable (y(t)) or the set point (YSET). The bias value is selectively updated as a function of the error signal (e(t)) to force the error signal (e(t)) toward zero.
