Abstract

The invention relates to the technical field of synchronous control, and particularly discloses a double-way opening synchronous deviation correcting method and system based on a ceramic rod sensor. The method comprises the steps of integrating an opening phase difference value, a deviation value tolerance, an opening deviation standard value and a peak value change interval to determine an opening synchronous state, generating a net deviation value, taking the net deviation value as a basis for judging the opening synchronous state, determining a deviation correction interval according to the duration of an unsynchronized state, and executing double-way opening deviation correction operation in the deviation correction interval by taking a polarizing time point as a basis. According to the invention, the instantaneous amplitude value of the opening phase difference value and the periodic variation characteristic thereof are taken as judgment basis to distinguish the inherent transient fluctuation and real continuous asynchronous state of the system, so that the accuracy and reliability of the judgment of the opening synchronous state are improved, and the accuracy of identifying the opening deviation state is improved by filtering random noise or sudden interference signals of the ceramic rod sensor.
