摘要：
The traditional tracking differentiator can only track the input signal in first-order indiscrimination degree. This article proposes the cascade form of third-order tracking differentiator with α-order indiscrimination degree based on α-order linear tracking differentiator. The minimal realization dimension of the presented third-order tracking differentiator with α-order indiscrimination degree is 2α. According to the minimal realization forms, the estimation value of input signal and its each order differential signal could be directly achieved. Simulation experiments show that the differentiator can increase the abilities of tracking higher order input signal.
