Experimental Validation of D-Q Model of Induction Motor for Advanced Control Applications
摘要
The three-phase induction motor forms the workhouse in industries. It finds application in paper mills, textile mills, robotics, centrifuges, and electric vehicles. These applications need high-precision control. For high-precision control, either vector control or direct torque control is preferred. The efficient modelling of induction motor assumes importance for effective control. The dynamic model, namely, d-axis and q-axis (d-q) model, is preferred as both the steady state and dynamic characteristics of induction motor can be studied. The d-q model is also found to be suitable for high-precision control applications. In this paper, the d-q model is developed for induction motor and validated through both MATLAB simulation and experimental hardware setup. The analysis is carried out on 2.2KW induction motor. The results obtained are presented.
