the derivative of step signal is infinite at saltation points,traditional method of discrediting step signal is not to achieve this in the realization of PID control simulation,in this paper,an improved discretization step signal is adopted,based on energy compensation thinking,finally,examples are given to demonstrate the effectiveness to reduce the error.
