| 英文摘要 |
| A partial-state feedback direct model reference adaptive control is designed for uncertain linear systems.
Detailed stability analysis and output tracking performance are presented. The design of the controller is based on the
reduced order observer and parameterization method. The novel scheme adopts feedback control. Feedback signals are not
only depend on the full state information or the output signals, but also on any measurable signals whose order is no more
than system dimension. Thus, partial-state feedback control as a new control scheme includes state feedback control and
output feedback control, and reduces more constraints on state information than state feedback control does and decreases
complexity of control structure compared to output feedback control. By introducing auxiliary signals, the existence of
output matching condition, boundedness of all closed-loop system signals and performance of asymptotic output tracking
are proved. The simulation results verify the effectiveness of the proposed scheme. |
