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.

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.
