Thus, estimator error [??] and NN weight error [??] are UUB.
are satisfied for each i, j, and r, then the closed-loop system is UUB, and the [H.sub.[infinity]] control performance (18) is guaranteed as prescribed [[rho].sup.2].
which means the system state x, control input u, and critic NN weight error [[??].sub.c] are all uniformly ultimately bounded (UUB).
From (49) and 50), we can see that the position and velocity tracking errors are cooperatively UUB and the ultimate bounds can be made as small as possible by appropriately tuning the design parameters.
Then all of the signals such as ex, [mathematical expression not reproducible] are guaranteed UUB properties.
(2) According to the Lyapunov methodology, the online weights updating laws of DNN are developed to accommodate the identification and to guarantee that the error between the DNN identifier and the real unknown systems is UUB.

If 0 < ([rho] + [m.sup.2])[[mu].T.sub.1.][[mu].sub.1] [less than or equal to] I holds, the estimation error as well as the generalized disturbances is uniformly ultimately bounded (UUB) [38].
In this case, we have the following ultimately uniformly bounded (UUB) tracking control result.
