摘要
研究了含摩擦环节伺服系统中出现的混沌振荡现象，说明了该系统通向混沌的道路．根据数值计算结果分析了摩擦力及系统参数对混沌行为的影响，并给出了系统的相图、时间历程及功率谱．
The chaotic oscillation of the servo system with friction governed by PD controllers is studied. Also, the route of this system transition into chaos is described. Finally, the impact of friction and other parameters on the chaotic oscillation of this system is analyzed, with the phase plane plots, time series and power spectral density given.
