Develop a servo actuator system adaptive sliding mode controller

Adaptive Sliding Mode Control (ASMC) for a servo actuator system with friction is investigated and addressed within the scope of this paper. The ASMC system offers several advantages over conventional sliding mode control. The first step is to reduce the control attempt to the lowest level permitted by the sliding mode’s preconditions. Second, knowing the highest uncertainty limits is not necessary for advancement. Using numerical simulation in MATLAB 2021a, it was possible to investigate the effectiveness of the proposed robust adaptive sliding mode control approach for servo actuator systems that contain friction. Comparing the results of ASMC (Adaptive Sliding Mode Control) to those of conventional SMC (Sliding Mode Control) reveals that the control attempts and chattering are reduced; however, the primary characteristics of the ASMC (Adaptive Sliding Mode Control) remain. To compensate for the system’s uncertain non - linearities, linear uncertainties, and, most importantly, non-linear uncertain variables caused by the different original control volumes, the scheme combines the sliding mode control method with the development of a novel-type Lyapunov function to create an asymptotic stability adaptive controller and adaptation laws. The results demonstrate that, when combined with the adaptation scheme, the non-linear control method achieves satisfactory performance on the designated tracking task even in unknown non-linear factors.
