    摘要: A cabin pressure control system (100) and method that reduces or inhibits gear train (138) backlash and the concomitant cabin pressure oscillations associated therewith. The cabin pressure control system (100) includes a variable proportional-integral (PI) controller (102) that implements a proportional function with a variable gain term and an integrator function with variable saturation limit. The proportional function gain term is increased, and the integrator saturation limits are decreased, at relatively low cabin error rate magnitudes. Increasing the proportional function gain term at relatively low cabin error rate magnitudes offsets potential backlash effects from the gear train (138). Decreasing the integrator saturation limits at relatively low cabin rate error magnitudes reduces potentially excessive integrator wind-up levels, which reduces the likelihood of producing limit-cycling and the potential for cabin pressure oscillations.

    摘要: There is provided a system configuration capable of evaluating stability of output from a user control system including various affects such as unknown motion characteristic and external turbulence and guaranteeing stability of the output from the user control system in spite of the unknown motion characteristic and external turbulence. That is, the control system having a virtual power monitor for realizing the function of evaluating/analyzing stability of a control object includes: a conservative control rule (104) capable of receiving a feedback signal from a user control object (3) and inputting an operation amount to the user control object (3) in a user control system (2') where the user control object (3) is controlled by a user control rule (5); and a virtual power monitor (110) for observing power virtually transmitted from the conservative control rule (104) to the user control object (3). Thus, it is possible to evaluate stability of the output from the user control system (2').

    摘要: A method, system, and computer program are provided for operating a valve using a cushion filter. The method, system, and computer program receive a process variable signal associated with operation of a valve. The method, system, and computer program filter the process variable signal to produce a filtered process variable signal using a cushion filter. The cushion filter implements a cushion in a bias used by the cushion filter. The method, system, and computer program generate an output signal for adjusting the valve based at least partially on the filtered process variable signal.

    摘要: A control for a modeled plant is provided. The modeled plant is represented by a model expression that is based on an input into the plant, an output from the plant, model parameters, and an estimated value for disturbance that is applied to the plant. The model expression includes a term in which the estimated disturbance value is multiplied by at least one of the model parameters. The model parameters are identified. The estimated disturbance value is calculated so that an error between a model output that is calculated based on the model expression and an actual output of the plant is minimized. The input into the plant is calculated based on the model expression so as to control the plant. Thus, the estimated disturbance value is directly reflected in the input into the plant without being calculated by any of the model parameters.
