摘要

摘要: 针对存在执行器故障的不确定非仿射动态系统,研究其跟踪控制问题. 在不太苛刻的Lipschitz条件下,提出了一种成本低、易于设计的用户友好类似比例积分(Proportion integration, PI)的控制策略, 和传统PI控制方法不同,这里的“比例”“积分”增益的确定无需反复试凑过程, 并且在系统可能出现执行器失效故障的情况下可以确保稳定跟踪.

Abstract: This work investigates the tracking control problem of nonaffine dynamic systems in the presence of modeling uncertainties and unpredictable actuation failures. Under the mild Lipschitz condition, a low-cost and user-friendly PI (Proportion integration)-like control scheme is developed without involving the time-consuming “trial and error” process for determining control gains as with a traditional PI control. Furthermore, the proposed control is fault-tolerant in the sense that stable tracking stability is still maintained without the need for re-adjusting control parameters even if the actuator loses its actuation effectiveness during system operation.
