Terminal Iterative Learning Control Applied to Thermoforming Machine Reheat Phase

This paper shows the use of terminal iterative learning control (TILC) algorithm to control the plastic sheet reheat phase of thermoforming machine. We use TILC as cycle to cycle control because we want to improve the adjustment of heater temperature setpoint that is actually done manually. We introduce the model of a thermoforming machine and the TILC algorithm tested on a thermoforming machine. Experimental results are included to show the effectiveness of the control
