摘要
由于阶跃信号在突变时,其导数为无穷大,实现PID控制仿真的过程中,传统的阶跃信号离散化方法,不能有效地体现这一点,本文提出一种改进的阶跃信号离散化方法,基于"能量补偿"思想,并通过实例验证,该方法能有效地减少仿真误差。
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.
