Previewing control system of automatic height adjustment for drum-type coal excavator based on memory cutting with identification of object model by genetic algorithm

摘要

A preview control system is applied to the process of automatic height adjustment for the roller of a drum-type coal excavator. The memory track is fully utilized as previewing information. The control problem of the lagged inertia of the coal excavator is solved in a radical way. Also, the performance index is optimized at the same time. For the preview control requests object model, we use a genetic algorithm to identify the model.
