Aiming at the influence of the inherent hysteresis characteristics of the piezoelectric ceramic actuator on the positioning and control accuracy, a linear equation antihysteresis method based on cutting rate is found. Firstly, the sampling points of the rising and falling trajectories of the hysteresis curve and the cutting rate ratio of the target correction line are calculated, the ratio is the cutting rate coefficient β. The relationship curve between the sampling voltage and corresponding β is fitted segmentally into a linear equation group. Finally, the sampling voltage is inputted into the equation group to obtain the correction voltage, and the driving control curve is made. Experiment results: with the above antihysteresis principle, the maximum hysteresis error of the driver is reduced from 14543% to 1268%, the repeatability error is less than 1497%, and the nonlinear error is less than 4497%. Experiment conclusion: compared with the cumbersome and complex modeling algorithm, the proposed method can realize the correction of the hysteresis curve with the form of proportional amplification and addition operation circuit. The algorithm is only oneorder equation group, which has higher implementation feasibility and operability. The algorithm provides a scientific reference for further improving the positioning and control accuracy of piezoelectric ceramic actuators.
