| description | The invention relates to a tool face angle adjusting and correcting system and method, and belongs to the technical field of automatic control. The system comprises a correction parameter calculation module, an adjustment effect evaluation module and an adjustment step length calculation module. The adjustment step length calculation module adjusts the matching degree and the reference step length in real time according to the stratum condition, solves the current tool face angle adjustment step length in real time, decomposes the angle to be adjusted, and achieves automatic step-by-step and accurate adjustment. In the process of solving the correction coefficient, on one hand, the maximum value and the minimum value of fuzzy processing are used, on the other hand, the maximum probability value interval is divided into a plurality of sub-intervals, the arithmetic average value of each sub-interval is calculated, and subsequent calculation is carried out by using the arithmetic average value.
