| 摘 要： | 设计一种快速收敛的非线性跟踪-微分器,使系统在远离平衡点和接近平衡点都能自动快速地向平衡点收敛,并采用线性与非线性组合的连续函数形式,而不需要切换函数,从而防止了系统的抖振现象.

| Abstract: | A fast-paced nonlinear tracking-differentiator was designed. It could guarantee that the state converges automatically to the equilibrium point with high speed under the condition that the state was far away from the equilibrium point or near to it. The continuous-function combination of linearity and nonlinearity was adopted, instead of the switching control by switch functions. As a result, this nonlinear tracking-differentiator prevented the chattering of the system. |

| Keywords: | converge nonlinear tracking-differentiator equilibrium point switch function chattering |
