Fig. 3 shows the system output, solid line is FSPSMC,dashed line is PID. From this figure, it is obvious that thecontrol performance of FSPSMC is better than that of PID.Note that there are no residual errors under constant externaldisturbance. It shows that the feedforward control is effective.Due to the system uncertainty, Smith predictor can not workwell, the feedback control algorithm is required to guaranteethe system performance. SMC has strong robustness anddisturbance suppression ability. Hence, it can achieve betterperformance than that of PID. Fig. 4 is the control input ofFSPSMC. From this figure, one can see the chattering isreduced greatly in light of integral switching gain technique
Being translated, please wait..
