It can guarantee the global boundness of closed loop signals and make the output tracking error arbitrarily small.
它能保证闭环系统信号的全局有界性，并使输出跟踪误差任意小。

The controllers are robust to some nonlinear uncertainties and bounded disturbance, and can ensure the global boundness of all closed loop signals.
该控制器对非线性不确定性和有界干扰具有鲁棒性，并能保证闭环系统信号的全局有界性。

Som criteria on the asymptotic behavior (such as boundness, tending to zero) of solutions for a kind of third order delay functional differential equation are established.
