Research on Error Compensation Property of Strapdown Inertial Navigation System Using Dynamic Model of Shearer

The strapdown inertial navigation system (SINS) can be installed on a shearer and used for monitoring its position.However, under the complex environment of the mechanized mining face, the strong vibration of the shearer may cause large calculation error.First, the dynamic model of a double-drum shearer is built with a force analysis, and the spect
