Abstract

For traditional typewriters, due to the low accuracy of the servo motor applied in the Z-axis, the pen may not reach the correct position. This project aims to improve the precision and robustness of the output of the traditional 3DOF typewriter by redesigning the gripping device based on fuzzy PID control. The desired positioning problem can be transformed into maintaining a constant force between the pen and the paper. In this way, to accomplish the fuzzy PID logic control, a twophase hybrid stepper motor is used to replace the servo motor, a transmission device based on a gear set is designed to amplify the motion, and a high-accuracy force feedback instrument is added to provide force feedback information. Design and virtual simulation experiments in micro-stepping operation are implemented in detail to track the transformed force problem in this paper. With mathematical models, the control problem exhibits dynamic uncertainties and nonlinearity. Some well-expected performances of the fuzzy PID controller are presented to show the success of improving the stability of the output.
