Development of Load Torque Estimation and Passivity Based Control for DC Motor Drive Systems with Reduced Sensor Count | Chapter 01 | Emerging Issues in Science and Technology Vol. 3
In this proposed work, Passivity Based Control (PBC) is selected for
performing trajectory tracking control of DC motor. In PBC, Exact Tracking
Error Dynamics Passive Output Feedback (ETEDPOF) method is preferred for buck
converter-fed DC motor drive system. Under load conditions, load torque
estimation is required to implement ETEDPOF. Also, load torque estimation is
completed without using torque and speed sensor which reduces space and cost of
the system. In load torque estimation, sensorless load torque estimation using
online algebraic approach for buck converter with DC Motor as load is designed
and developed. Further, the performance of Sensorless online Algebraic Approach
(SAA) is compared with Sensorless Reduced Order Observer (SROO). Results are presented
to validate the features of proposed schemes.
