摘要

研究了具有执行器故障和有界扰动的连续时间切换仿射系统的${\mathcal {L}}_{\infty }$无碰撞传递容错控制问题。设计了一种新的分段过渡相关容错控制器，通过施加指定的凸点限制约束，得到了满足新的平均停留时间约束的容错控制器存在的充分条件，保证了闭环系统的实际稳定性和发生切换和故障时的无凸点转移。最后，以直流-直流升压变换器为例，验证了所提方法的实用性和有效性。

Fault Tolerant Control of Switched Affine Systems With Application to Boost Converter: The Transition-Dependent Bumpless Transfer Approach

The

${\mathcal {L}}_{\infty }$

bumpless transfer fault-tolerant control problem is addressed for continuous-time switched affine systems with actuator faults and bounded disturbances. A novel piecewise transition-dependent fault-tolerant controller is designed, by enforcing the specified bumps limitation constraints, sufficient conditions for the existence of the fault-tolerant controller are derived satisfying a new average dwell time constraint, which guarantees the practical stability of the closed-loop system and the bumpless transfer as switching and faults occur. Finally, both practicability and validity of the developed methods are illustrated through a case study of DC-DC boost converter.
