1. A mining system comprising:
a shearer;
a conveyor;
a first sensor operable to generate a first signal related to a position of the shearer;
a second sensor operable to generate a second signal related to a load of the conveyor;
a first drive mechanism coupled to the shearer and operable to drive the shearer; and
a controller operable to
receive the first signal from the first sensor,
determine the position of the shearer based on the first signal,
receive the second signal from the second sensor,
determine the load of the conveyor based on the second signal,
determine an output of the mining system based on the position of the shearer and the load of the conveyor, and
control a speed of the shearer based on the output of the mining system.
