| Abstract: | Aiming at the low-speed friction servo system,a design method of sliding-mode control using exponential approach law is presented to drive the system to reach the equilibrium point in finite time so that this can shorten the appulsive time. And the design can weaken chattering phenomenon due to the adduction of the saturated function. At last, based on the Matlab/Simulink platform,Simulink indicates that the control method improves the tracking accuracy considerably and is robust. |
