A control system simultaneously controls a multi-zone process with a self-adaptive model predictive controller (MPC), such as temperature control within a plastic injection molding system. The controller is initialized with basic system information. A pre-identification procedure determines a suggested system sampling rate, delays or “dead times” for each zone and initial system model matrix coefficients necessary for operation of the control predictions. The recursive least squares based system model update, control variable predictions and calculations of the control horizon values are preferably executed in real time by using matrix calculation basic functions implemented and optimized for being used in a S7 environment by a Siemens PLC. The number of predictions and the horizon of the control steps required to achieve the setpoint are significantly high to achieve smooth and robust control. Several matrix calculations, including an inverse matrix procedure performed at each sample pulse and for each individual zone determine the MPC gain matrices needed to bring the system with minimum control effort and variations to the final setpoint. Corrective signals, based on the predictive model and the minimization criteria explained above, are issued to adjust system heating/cooling outputs at the next sample time occurrence, so as to bring the system to the desired set point. The process is repeated continuously at each sample pulse.

An improved method of preparing molded seamless breast pads, cups, fronts and the like for use in brassieres and other garments is described. Polyurethane foam sheet, which still contains free isocyanates in its urethane matrix, is sliced from a freshly made foam bun, and placed between the mold parts. The mold parts are then closed by a hydraulic press. Steam is injected through holes in one mold part, and flows throughout the compressed polyurethane foam. Exhaust steam is emitted from holes in the other mold part. Moisture and heat from the steam then accelerate reactions with the free isocyanates and further cure the polyurethane foam material. The polyurethane foam material is therefore molded into the shape of mold parts cavity.
