Claim 0:
1. A method for controlling a tire curing bladder in a tire curing press, comprising:
measuring a plurality of performance parameters for each of a valve output signal controlling a pressure control valve supplying a source of pressurized fluid to the tire curing bladder and a pressure within the tire curing bladder during a previous duty cycle of the tire curing press;
storing the plurality of performance parameters as a data array representing a plurality of temporal positions within the previous duty cycle;
analyzing the plurality of performance parameters to determine a corrected valve signal output to obtain a desired setpoint within the tire curing bladder;
adjusting the valve output signal to the corrected valve signal output to reduce one or more of an overshoot condition and an undershoot condition of the pressure from the desired setpoint, wherein the corrected valve signal output at a selected temporal position in a subsequent duty cycle comprises the valve output signal in the previous duty cycle at a corresponding temporal position in the previous duty cycle and an error correction value for the corresponding temporal position in the previous duty cycle; and
applying the corrected valve signal output to the pressure control valve during the subsequent duty cycle.
