1. An adaptive control method based on train operating condition identification, comprising:
acquiring operating state data of a train under different traction conditions by adopting a multi-sensor fused adhesion characteristic state self-calibration observer and calculating to obtain traction and braking performance data:
combining the traction and braking performance data, line information data and operating control information to form a multi-sensor fused adhesion condition characteristic related data set;
dividing, based on the adhesion condition characteristic related data set, train adhesion conditions into Nz grades by adopting a fuzzy clustering-based false nearest neighbors algorithm, wherein Nz is a natural number, and
