| 针对具有传感器故障的一类严格反馈非线性系统, 提出一种有限时间自适应动态面容错控制策略. 考虑的
传感器故障包括: 固定偏差故障、漂移故障、精度下降及失效故障. 以反步法为主要设计依据, 利用模糊逻辑系统处
理模型中的未知函数. 该控制策略的显著优势在于结合有限时间理论、容错控制、模糊逻辑控制及动态面控制, 使
得系统无论发生故障与否, 均使得系统在原点处是半全局实际有限时间稳定, 同时保证系统的实际输出信号在有限
时间内跟踪期望信号, 且跟踪误差收敛于坐标原点的小邻域内. 另外, 通过采用动态面控制技术克服了传统反步法
中的计算复杂问题. 最后, 仿真算例证明了该设计方案的有效性. |
| 英文摘要 |
| A finite-time adaptive dynamic surface fault-tolerant control strategy is proposed for a class of strict-feedback
nonlinear systems with sensor faults. The sensor faults considered include: fixed deviation fault, drift fault, precision decline
and failure fault. Based on the backstepping method, the fuzzy logic systems are used to deal with the unknown functions
in the model. The significant advantage of our proposed strategy is to ensure that the system is semi-globally practically
finite-time stable at the origin regardless of failures by using finite-time theory, fault-tolerant control, fuzzy logic control
and dynamic surface control, and the actual output signal of the system is guaranteed to track a desired signal in finite
time, and the tracking error converges to a small neighborhood of the coordinate origin. Moreover, the complex calculation
problem, which exists in the traditional backstepping method, is overcome by using the dynamic surface control. Finally,
the effectiveness of the proposed scheme is proved by a simulation example. |
