A Joint Positioning and Attitude Solving Method for Shearer and Scraper Conveyor under Complex Conditions JiachengXie, 1,2 ZhaojianYang, 1,2 XuewenWang, 1,2 ShupingWang, 1,2 andQingZhang 1,2 The key to solving these issues is to determine support's working resistance of the FMFLMH. In this paper, comprehensive theoretical analysis, numerical simulation, and field observation were applied to determine the support's working resistance in the FMFLMH based on movement type of the first subordinate key stratum (SKS 1). Nevertheless, both algorithms are able to significantly decrease the vibration error (64.5% and 74.7% less coning error and 37.5% and 69.6% less sculling error than without compensation) of agricultural machinery by using SINS. Finally, experimental results indicated that positioning accuracy of SINS can be increased with three samples and four samples compensation algorithms, and its accuracy was superior to that with non-compensation model. Finally, the experimental results show that the multi-model intelligent switching fault-tolerant positioning algorithm can effectively overcome increased positioning error of tightly-coupled model and decision tree model based on these two invalid styles. 2.
