摘要
对自发动机转速信号提取转速加速度信息的微分算法进行了研究,对比、分析了跟踪微分器和传统一阶差分算法的性能差异。在此基础上,提出了基于转速补偿的双跟踪微分器算法。仿真研究表明,这一双跟踪微分器的跟随性和稳定性均较为理想。
A differential algorithm for extracting acceleration information from the speed signal of engines is re- searched. Firstly, the difference in performance between the tracking differentiator and the traditional first-order differential algorithm is analyzed and compared, and then a dual tracking differentiator based on the speed com- pensation is presented. The simulation results show the proposed dual tracking differentiator is more satisfactory in the traceability and stability.
