    Abstract: In one example embodiment, an apparatus for providing negative-pressure therapy may comprise a negative-pressure source, a pressure sensor, and a control valve. The negative-pressure source may be configured to be fluidly coupled to a distribution component. The control valve may be fluidly coupled to the pressure sensor and configured to be selectively coupled to the negative-pressure source, the distribution component, or both. A controller may also be configured to operate the control valve to selectively couple the pressure sensor to at least one of the negative-pressure source and the distribution component through the control valve, and the pressure sensor may provide a feedback signal to the controller indicative of pressure in a feedback path associated with the position of the control valve. The controller may also be configured to operate the negative-pressure source based on the feedback signal.

    Abstract: In one example embodiment, a system for stimulating healing of tissue at a wound site is disclosed. The system comprises a dressing including a porous pad and a drape covering the pad at a wound site for maintaining negative pressure at a wound site, a negative-pressure source including a pump and an electric motor to generate a pump pressure (PP) for applying to the wound site, and a first pressure sensor for sensing the pump pressure (PP). The system further comprises a controller coupled to the first pressure sensor and electric motor and including a PID controller that compares the pump pressure (PP) to a target pump pressure (TPP) and a bang-bang controller that controls wound pressure (WP) proximate the wound site, and wherein the controller is configured to alternatively select the bang-bang controller when the system is in a low-leakage condition or the PID controller when the system is in a high-leakage condition.
