Abstract

An observer based on external and internal dynamics is designed, making the error between observing value and factual value to zero. Moreover, a continuously high-gain sliding mode controller is presented by using a sliding mode state which can make the error between the output and reference signal converge to zero. The analysis of stability and the result of simulation indicate that the controller designed has strong robustness and rapid convergence.
