针对存在参数不确定与外部干扰的四旋翼无人机跟踪控制问题,提出了一种自适应抗饱和防奇异指定时间预定性能控制方法。首先,设计了自适应抗饱和防奇异指定时间预定性能函数,通过该函数设计参数的选择实现了系统暂稳态性能态要求,使跟踪误差在任意指定时间Tρ内收敛,通过调节设计参数b,有效避免了执行器饱和,无需额外抗饱和补偿器;其次,设计了自适应调整项,确保跟踪误差始终约束在预设范围内,避免了系统因突变扰动引发奇异性问题,并且采用自适应方法巧妙地解决了系统参数不确定性与未知外部干扰的问题;接着,提出了事件触发控制机制,降低了通信和计算负担,减少了系统能耗。最后,基于李雅普诺夫稳定性理论证明了所设计控制方法的有效性,并且通过仿真验证了所提控制算法的有效性和优越性。

Fort the tracking control problem of quadrotor unmanned aerial vehicles (UAVs)under the conditions of parameter uncertainties and external interference,an adaptive anti-saturation and anti-singularity appointed-time prescribed performance control method is proposed.Firstly,an adaptive anti-saturation and anti-singularity appointed-time prescribed performance function is designed.The transient and steady-state performance requirements of the system are achieved by selecting the design parameters of this function,ensuring that the tracking errors converge within any appointed time Tρ.The actuator saturation is effectively avoided by adjusting the design parameter b without additional anti-saturation compensators.Secondly,an adaptive adjustment term is designed to ensure that the tracking errors are always constrained within the preset range,thereby avoiding the singularity problems caused by sudden disturbances in the system.Moreover,the issues of system parameter uncertainties and unknown external disturbances ingeniously resolved using the adaptive method.Subsequently,an event-triggered control mechanism is proposed to reduce the communication and computation burdens and decrease the system energy consumption.Finally,the effectiveness of the designed control method is proved based on the Lyapunov stability theory,and the effectiveness and superiority of the proposed control algorithm are verified through simulation.
