Zero-position online adjustment method of servo mechanism

The invention, which belongs to the field of servo control technology, specifically discloses a zero-position online adjustment method of a servo mechanism. The method comprises the following steps: S1, receiving a ''zero position configuration switch'' instruction; S2, parsing the ''zero position configuration switch'' instruction in the step one; S3, receiving a ''zero configuration'' instruction; S4, analyzing the ''zero configuration'' external interruption instruction in the step three; S5, loading a configuration parameter; and S6, introducing the loaded configuration parameter in the step five into a PID control algorithm of a servo mechanism to realize online adjustment of the zero position of the servo mechanism. With the method disclosed by the invention, the zero offset of the servo mechanism can be eliminated; the reliability and stability of the servo system can be improved; and the zero-position online adjustment method is easy to realize. 本发明属于伺服控制技术领域，具体公开种伺服机构的零位在线调节方法，该方法包括以下步骤：步骤S1：接收到"零位配置
