一类非仿射系统的PI-like容错控制
PI-like Fault-tolerant Control of Nonaffine Systems with Actuator Failures
摘要
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.关键词
