For energy-conservation in temperature control, the overshoot should be decreased. To overcome this, we newly developed a function to adjust the overshoot against disturbances. In this paper, this new control system for adjusting the overshoot against disturbance is described. as well as the test results to show the overshoot suppression effects in packing machine temperature control. As a result, we confirm that this new control system can realize a 50% reduction of the time takes until the temperature gets stable.
