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.
