Abstract: Systems and methods are provided for designing a compensator for controlling a plant and to control systems for such plants. In one embodiment, a compensator may be designed by introducing a predetermined input into the plant; measuring an impulse response of the plant responding to the predetermined input; determining a mathematical model for the plant based at least in part on the impulse response of the plant, the model comprising a first ratio of polynomials (the plant model) including a first set of coefficients; and determining a second ratio of polynomials including a second set of coefficients (the compensator) based at least in part on the first set of coefficients to operate the compensator such that the compensator produces a series of plant inputs to move the plant towards a setpoint according to a predetermined plant output.

Abstract: Disclosed is an apparatus, system, and method for compensating for hydrostatic pressure offset in transducer-based pressure measurements. The system may comprise: a measurement pressure transducer to measure an apparent fluid pressure at a measurement site, a reference pressure transducer to measure a hydrostatic pressure caused by a level difference between the measurement pressure transducer and the measurement site, and a controller to generate a corrected fluid pressure measurement based on the apparent fluid pressure and the hydrostatic pressure, wherein the measurement pressure transducer and the reference pressure transducer are placed at a same first level, and the measurement site and an end of a fluid-filled tube connected to the reference pressure transducer are at a same second level.

Abstract: Disclosed is an apparatus, system, and method for utilizing a pressure transducer simulator that is configured for use with a pressure sensor device and a patient monitoring device. The pressure transducer simulator may be configured to generate a simulation of the output of an analog pressure sensing device to be compatible with the patient monitoring device. The simulation may be based upon a pressure signal received from the pressure sensor device. In one embodiment, the pressure transducer simulator includes a digital potentiometer that is configured to generate an analog signal based upon the pressure signal received from the pressure sensor device and wherein the digital potentiometer is configured to transmit the analog signal to the patient monitoring device.
