Abstract :
Time delay filter (TDF) and time delay observer (TDO) are combined together to achieve fast system response without residual vibration in LTI-SISO systems with uncertainties. The time delay observer is used as a feedback control to resist disturbances and parameter variations, and time delay filter is used to suppress residual vibrations, which is placed outside the closed-loop system. Simulation results demonstrate the effectiveness of his method.
