Control of Uncertain LTI Systems Based on an Uncertainty and Disturbance Estimator

  title={Control of Uncertain LTI Systems Based on an Uncertainty and Disturbance Estimator},
  author={Qing-Chang Zhong},
This paper proposes a robust control strategy for uncertain L systems. The strategy is based on an uncertainty and disturb estimator (UDE). It brings similar performance as the time-del control (TDC). The advantages over TDC are: (i) no delay introduced into the system; (ii) there are no oscillations in t control signal; and (iii) there is no need of measuring the deriv tives of the state vector. The robust stability of LTI-SISO system analyzed, and simulations are given to show the… CONTINUE READING
