This paper proposes a modified Time Delay Controller for a class of uncertain nonlinear system. The controller uses delayed inputs and delayed derivative of some of the state variables to estimate the uncertain dynamics. To attenuate the noise amplified by the differentiation, the delay time is chosen to be much larger than the sampling period. Keeping the delay time at an appropriate level, the performance of the system is improved significantly by reducing the sampling period without further… CONTINUE READING
