    摘要: Heating of hot melt adhesive in a hot melt dispensing system is provided by heaters distributed in a plurality of zones of the system. A controller receives input electric power and distributes that electric power to the heaters on a time sharing basis. The controller delivers power to the heaters as a function of the total current target, a temperature set point, the current draw of each of the heaters, and stored priority criteria such as heating priorities of the zones, a history of on and off periods for each heater, and distance from the temperature set point.

    摘要: The control method uses the following scheme: Control Value (CV) = Proportional Value (PV) + Derivative Value (DV) + Derivative Correction (DC), where PV goes from 0 to MAX and operates over a very narrow band - in a temperature control example plus or minus 1 degree C from the setpoint and is used to stabilize CV and enforce the setpoint. DV goes from -MAX to MAX and is exponentially decayed over a time constant to weigh the most recent values heavier than older values. This allows the control to see the real derivative despite a large step size which might otherwise mask it and within a small time window. DC goes from -MAX to MAX and makes this scheme work for any situation. The desired derivative is defined based on the graph. This then adjusts to compensate when the slope is not following the ideal definition.
