| Abstract: | The phenomenon of limit cycle was observed in low-velocity servo system. With the help of nonlinear analysis tools, this paper analyzes the kinetics of limit cycle and finds out the reasons that induce this phenomenon. First, the Stribeck model was converted to piecewise linearized friction model and the state space model was also obtained. Then, by analyzing the feature of the system balance point and using Poincare-Bendixson theorem, the existence of the limit cycle was proved. The region where the limit ... |
