Systems and methods for adaptively tuning a Proportional, Integral and Derivative (PID) controller in a zero order industrial process are provided. A method and system can involve receiving input data at one or more inputs of the PID controller and generating output data at one or more outputs of the PID controller in response to processing the input data. Error(s) associated with the controller are determined based on an analysis of a measured parameter with respect to a desired setpoint. The measured parameter may be indicated in the output data. Adaptive gain may be applied to the PID controller in response to the absolute value of the controller error both exceeding a deadband and increasing. Additionally, normal gain, which is lower than the adaptive gain, may be applied to the PID controller in response to the absolute value of the controller error either being below the deadband or decreasing.

Adaptive PID gain for a zero order process

A method for generating nitric oxide is disclosed in one embodiment in accordance with the invention as including the steps of providing a solid tablet comprising non-deliquescent reactants and heating the tablet with a heat source to melt at least one of the reactants to promote reaction thereof, thereby generating nitric oxide, and mixing the nitric oxide with diluent gas to provide a therapeutically safe concentration of nitric oxide.

Nitric oxide generator and non-deliquescent tablet for use in same

A method to generate nitric oxide is disclosed in one embodiment in accordance with the invention. A tablet may be placed within a vessel such that it is in thermal communication with a heat source to receive heat therefrom. The tablet is then heated to melt at least one reactant forming the tablet. The tablet may contain reactants that are substantially non-deliquescent and form nitric oxide in response to heat from the heat source.
