Sensorless Speed Control of Induction Motor Drives Using Disturbance Observer and Adaptive PID Controller

This study discusses the development of a sensorless speed control method for induction motors using an adaptive PID Controller. An approach is proposed that utilizes a disturbance observer to estimate the speed of the induction motor. Subsequently, an adaptive PID Controller is implemented to regulate speed control with real-time parameter adjustments based on the motor's operating conditions. Experimental results show that the combination of these two methods enhances dynamic response performance, particularly in avoiding overshoot and steady-state error. By applying this technique, effective control is achieved without the need for additional sensor devices, leading to reduced costs and system complexity. This research makes an important contribution to the development of more efficient and reliable induction motor technology and opens avenues for further research in sensorless control applications.
