| 英文摘要 |
| Aiming at a class of nonlinear multi-agent systems with unknown states and hysteresis input, a distributed
output feedback asymptotic consensus adaptive control scheme based on leader-follower is proposed in this paper. First, the
K-filters with dynamic high gain are constructed to estimate the unknown states of the multi-agent systems. Then, a new
dynamic surface control strategy is adopted to design controller. The nonlinear filters with a positive time-varying integral
function are designed, which are different from the first order low pass filters adopted in the traditional dynamic surface
control strategy. This filter can not only solve the problem of “differential explosion” and reduce the computational burden,
but also it can compensate the boundary layer error of the traditional dynamic surface and make the tracking error converge
to zero. Theoretical analysis shows that the control scheme can effectively eliminate the effects of unknown hysteresis,
ensure the stability of the whole closed-loop system and make the tracking error reach the goal of asymptotic convergence.
Finally, the effectiveness of the proposed control scheme is analyzed and verified by simulation. |
