不确定时滞系统的反馈H_∞滤波设计

Feedback Filtering for a Class of Uncertain Systems with Time-varying Delay

针对鲁棒H∞滤波问题,在不确定时滞系统中,考虑时滞函数是一致连续有界的情况。利用一个新的积分不等式,得到了新的时滞依赖的充分条件,设计一个合适的滤波器,保证滤波误差系统是渐近稳定的,且H∞干扰衰减在规定范围内。

For robust filtering problems,it is discussed that the time-varing delay is continuous uniformly bounded in uncertain time-varying delay systems.Using a new integral inequality,some new delay-dependent sufficient conditions are obtained and a suitable filter is designed,which guarantees that filtering error systems is asymptotically stable with a prescribed level of noise attention.
