  • Patent number: 11467543
    Abstract: A method for designing and tuning a PID process controller includes approximating a process as a second order process but in a manner that includes the effects or characteristics introduced by various different devices in the I/O network, and using a lambda tuning method to determine tuning parameters or coefficients for the PID controller. The enhanced controller design and tuning method provides a systematic manner of achieving performance improvement of PID controllers within a process control system and is effective at overcoming challenges arising from signal aliasing, the use of anti-aliasing filtering and the effects of different I/O settings of both traditional and advanced I/O marshalling architectures.

  • Patent number: 11415957
    Abstract: A ladder display system includes: a first controller having a first ladder program; and a second controller having a second ladder program that performs input/output processing with the first ladder program. An input/output signal table generating unit generates an input/output signal table relating an input/output signal of the first ladder program to an input/output signal of the second ladder program. An external reference execution unit specifies a signal of the second ladder program and requests transmission of at least a part of the first ladder program. A ladder program output unit transmits at least a part of the first ladder program including a signal corresponding to the specified signal to the second controller. A ladder program display unit displays at least the part of the first ladder program output by the ladder program output unit on the second controller.

  • Patent number: 10809589
    Abstract: This disclosure provides a window controller that includes a command-voltage generator that generates a command voltage signal, and a pulse-width-modulated-signal generator that generates a pulse-width-modulated signal based on the command voltage signal. The pulse-width-modulated signal drives an optically-switchable device. The pulse-width-modulated signal comprises a first power component having a first duty cycle and a second power component having a second duty cycle. The first component delivers a first pulse during each active portion of the first duty cycle, and the second component delivers a second pulse during each active portion of the second duty cycle. The first pulses are applied to a first conductive layer and the second pulses are applied to a second conductive layer. The relative durations of the active portions and the relative durations of the first and second pulses are adjusted to result in a change in an effective DC voltage applied across the optically-switchable device.
