Robust pid sliding mode control for dc servo motor speed control

This research proposes a Sliding Mode PID (SMC-PID) controller to improve the speed control performance of DC servo motors, which are widely used in industrial applications such as robotics and CNC. The objective of the proposed controller is to enhance the speed control performance of DC servo motors on the CE110 Servo Trainer. The proposed method integrates a traditional PID controller with a sliding mode control mechanism to effectively handle system uncertainties and disturbances. Experimental results show that the SMC-PID method provides significant improvements in accuracy and stability compared to traditional PID controllers, with metrics such as reduced overshoot, shorter settling time, and increased adaptability to system uncertainties. This research highlights the effectiveness of the SMC-PID controller, enhancing the performance of DC servo motor speed control.
