| 英文摘要 |
| This paper investigates the tracking control problem of a class of multi vehicle systems suffering from internal
disturbance of the leader and external disturbance of the follower. Taking the angle trajectory cooperative tracking problem
of a network of nonlinear 3–DOF helicopters as an example, a distributed robust algorithm is designed and verified, which
is based on the simultaneous estimation and compensation of the uncertainties acting on the leader and followers. By an
uncertainty and disturbance estimator and an extended state observer respectively, the estimation and compensation of input
disturbances are realized to recover the tracking performance of a nominal system. It is proved that the ultimate bounds of
tracking errors and closed-loop estimation errors depend monotonically on two key design parameters of the estimators, and
the condition for asymptotic tracking is derived. The effectiveness of the parameter-tuning mechanism and the necessity of
compensating both the internal and external disturbances for followers are demonstrated by a simulation comparison on a
system including four virtual helicopter models and by an experimental comparison on a system including both virtual and
real helicopter models. |
