Abstract :
A sliding motion can be divided into two phases: reaching phase and sliding phase. One of the features of sliding mode control is that it is robust to parameter uncertainties and external disturbances in the sliding phase. But in the reaching phase, SMC may be sensitive to parameter uncertainty and external disturbance. The moving sliding surface proposed by Choi et al can minimize or eliminate the reaching phase. In this article, the sliding mode fuzzy controller design method with a moving sliding surface is presented. The simulation results show the superiority of SMFC over classical SMC and PID controller in the presence of external disturbances.
