where uðx a Þ and uðx q Þ are the control inputs. This control system is single
input, so the inputs uðx a Þ and uðx q Þ are interlocked. Using the Generalized
Gronwall inequality and Laplace transform of the Mittag Leffler function,
the system was proven to converge to the equilibrium point E 1 at some con-
ditions on uðx a Þ and uðx q Þ. The first case is at uðx a Þ 5 ðm 2 55Þx a , uðx q Þ 5 0,
and m , 1. The second case is at uðx q Þ 5 ðn 2 4Þx q , uðx a Þ 5 0, and n , 4=55.
