    • A method of operating a control device having a setpoint value, an error signal, and a control output is disclosed. The error signal is representative of a difference between a controlled variable and the setpoint value, the control output operable to affect the controlled variable. The method includes generating the control output based at least in part on the error signal and holding the control output at a held value independent of the error signal when the error signal is within a dead zone. The method also includes causing an integrating portion within the control device to track the error signal and the held value when the error signal is within the dead zone.
    • 公开了一种操作具有设定点值,误差信号和控制输出的控制装置的方法。 误差信号代表受控变量与设定值之间的差值,控制输出可操作以影响受控变量。 该方法包括至少部分地基于误差信号产生控制输出,并且当误差信号在死区内时将控制输出保持在独立于误差信号的保持值。 该方法还包括当误差信号在死区内时,使控制装置内的积分部分跟踪误差信号和保持值。
