SUMMARY This paper proposes a new method for designing feedforward inputs for Galvano scanners in laser drilling machines. The heat generated by current amplifiers becomes a problem as the positioning speed of the Galvano scanner is increased. The proposed method involves the use of a final‐state control that considers the voltage constraint of a current amplifier. By constraining the applied voltage to the motor, the power supply voltage of the current amplifier is reduced. Therefore, the electricity consumed and the heat generated by the current amplifier can be reduced. The effectiveness of the proposed method is shown through simulation and experimental results.
