一类控制受限不确定系统的控制分配重构控制

针对一类控制受限的不确定性系统,提出了一种基于控制分配理论的重构控制策略。该重构策略充分考虑了作动器偏转受约束的情形,基于伪逆控制分配算法,利用自适应控制理论和李雅普诺夫稳定理论,设计了控制分配阵的自适应控制律,使得系统在作动器发生饱和的情形下自适应地调节控制分配阵,从而改变作用于作动器的控制指令,完成系统的重构任务。最后以某多操纵面战机模型为算例对算法予以验证,仿真结果表明了算法的合理性。

Control allocation reconfigurable control of a class of uncertain system with the control constrained

A reconfigurable control strategy based on control allocation for uncertain system with the control constrained is proposed.The strategy is considered the limitation of the actuator based on pseudo-inverse control allocation algorithm,using the adaptive control theory and Lyapunov stability theory to design for the adaptive control law of control allocation matrix which changes the actuator to complete the system reconfiguration tasks.Finally,the simulation results of a multiple effectors fighter model show that the algorithm is reasonable.
