Abstract
A novel polynomial tracking differentiator is presented in this paper to obtain the continuous signal and its derivative from the reference signal in real time. The proposed differentiator is a robust scheme and can suppress the chattering effect. The stability of the differentiator is verified by using the Lyapunov theory. Simulations are carried out and the results demonstrate that the tracking and differential errors can converge faster and a higher precision is achieved.
