摘要： A variable flow rate gas control valve for use in consumer and commercial appliances is presented. The valve utilizes two or more solenoids to control the operating position of two different valve members whose orifices are sized in an exponential relationship with one another. By opening one or more of the valving members in various combinations, a variable flow rate of gaseous fuel may be controlled in integer multiple steps from full off to full on. The solenoid configurations may be in line, opposing, or symmetrical about an axis of the valve. The number of unique flow rates (F) is related to the number of solenoids (N) as F=2N. The relationship between the size (S) of the individual gas control orifices for each of the solenoids is related to N by the relationship S=2n−1 for each individual gas control orifice (n) numbered 1 to N.

摘要： According to one embodiment, a flow rate adjusting unit is disposed on a gas passageway and includes a valve that adjusts the flow rate of a gas and an actuator that controls the displacement amount of the valve. A displacement amount storage unit stores displacement amount information in which a displacement amount of the valve, used when a gas flows into the gas passageway at a flow rate defined according to a process procedure before performing the process procedure, is obtained in advance for each process procedure. A setting circuit acquires the displacement amount corresponding to the process procedure from the displacement amount storage unit, and controls the actuator on the basis of the acquired displacement amount.

摘要： The multiple antisymmetric optimal (MAO) control algorithm is disclosed for a gas delivery system including a flow ratio controller for dividing a single mass flow into multiple flow lines. In the MAO control algorithm, each flow line is provided with a flow sensor and a valve actively controlled by a SISO feedback controller combined with a linear saturator to achieve the targeted flow ratio set point. For optimal control performance, these SISO controller and linear saturators are substantial identical. It is proved that each valve control command is multiple antisymmetric to the summation of all other valve control commands. Therefore, the MAO control algorithm guarantees that there exists at least one valve at the allowable maximum open position at any moment, which achieves the optimal solution in terms of the maximum total valve conductance for a given set of flow ratio set points.
