TIME DELAY OBSERVER WITH LOW-PASS FILTER FOR LTI-SISO SYSTEMS WITH UNCERTAINTIES
不确定LTI-SISO系统的低通滤波时滞观测器控制

Intentionally and reasonably using time delay may result in surprising performances. It has been proved that system uncertainties and disturbances can be observed with time delay observer to enhance the system robustness. The time delay observer with low pass filter is presented to eliminate the oscillations of control signal in this paper. Simulation results show that the time delay observer with low pass filter, which is capable of observing system uncertainties and disturbances almost immediately, is a good method of robust control.
