Nowadays, many belt conveyors are equipped with VSDs, where the VSD based optimal control strategy can be applied. For a belt conveyor with VSD, its power at the jth sample time can be expressed as P i j = f P (V i j, T i j) according to . Combining P i j with, we obtain the total electricity cost as follows (10) J = ∑ i = 1 n ∑ j = 1 N f ...
