Speed control of DC motor with fractional order sliding mode controller

Due to the fact that fractional order sliding mode controller (FOSMC) can show superior control performance compared to proportional and integral controller (PI), calcic sliding mode controllers (SMC) has started to attract the attention of researchers. The purpose of this control management is to reduce peak overshot, DC motor speed, torque overshoot and seating times based on variable construction systems. In the first step, the SMC and PI controllers were used to control the speed and torque of the DC motor. A model was developed using Matlab / Simulink and its simulation was designed. The next step and after mathematical extraction of equations representing the fractional order sliding mode control system in the same way, the controller was modeled The speed control of the DC motor using PI, SMC and fractional order mode control systems were studied and the results were compared. Furthermore, the analysis is performed according to the varying motor loads. In robotic applications, it is desired that the motors operating under load are not affected by the changes depending on the loading situation. According to the theoretical and simulation results obtained, the fractional grade shift mode control unit is superior to PI and SMC for DC motor speed and torque control. In addition, the FOSMC method showed a more robust behavior against disturbing effects. The desired speed was followed perfectly.
