基于Nussbaum函数的多无人机预设性能反步容错协同控制
Nussbaum-Based Prescribed Performance Backstepping Fault-Tolerant Cooperative Control of Multi-UAVs
摘要
Abstract
To address the safe flight control problem for multiple unmanned aerial vehicles(multi-UAVs)under actuator gain faults during cooperative mission execution,a decentralized fault-tolerant attitude tracking control scheme with pre-scribed performance is designed to achieve the attitude synchronization tracking control of multi-UAVs.Firstly,the atti-tude synchronization tracking error and angular rate tracking error are defined.Then,the inequality constraints of tracking errors are transformed into the equality forms by using the prescribed performance function.Moreover,the fault-tolerant attitude tracking controller is designed based on the transformed errors,and the Nussbaum function is used to solve the un-known control gain problem caused by the gain fault.Lyapunov stability analysis shows that the attitude tracking errors are convergent in the presence of faults.Finally,simulation results demonstrate the effectiveness of the control scheme.关键词
