This invention discloses a feedforward adjustment method, device, and storage medium for calibrating the consistency of host control execution, belonging to the field of mechanical automation control technology. The method includes: acquiring the control input signal and the actuator output signal during the feedforward system control process, and plotting a measured curve; selecting the dead zone endpoint from the measured curve as the calculation starting point and the extreme point of the actuator output signal as the calculation endpoint, and plotting a desired curve; equally dividing the measured curve and the desired curve into several sampling points to obtain the coordinate data of the measured curve and the desired curve, respectively; obtaining the linearity by calculating the average deviation; comparing the linearity with a preset linearity threshold; if the linearity is greater than the preset linearity threshold, then optimizing by adjusting the actuator input signal. This invention can improve the trajectory accuracy of the host robotic arm in complex high-speed conditions and solve problems such as poor accuracy and lag.
