| 英文摘要 |
| The carrier-based unmanned aerial vehicle (UAV) should be required to track the trajectory accurately and
ensured to have the transient performance during landing. And in this paper a constrained command prescribed control law
based on a new equivalent error model is designed. Firstly, a constrained command filter method is introduced to consider
the actual engineering problems such as rudder limited and angular rate limited. Secondly, the continuous hyperbolic
tangent function is used to approximate the saturation function, and an adaptive law is used to estimate the unknown
parameters with the modeling errors and a variety of environmental disturbance factors. Finally, the transient performance
during landing is emphatically analyzed by introducing prescribed performance method. The strong robustness and better
transient performance in complex environment is demonstrated by theoretical analysis and simulation. |
