The estimation of PID controller parameters of vector controlled induction motor using Ziegler-Nichols method

Abstract

Induction motors (IM) are commonly used in industrial applications due to their superiorities such as low cost, less maintenance requirements, high effiency and high power density in comparison with other electric motors such as dc motors. There are many studies in the literature on IM control. The best known speed control method of the IM is scalar control method (SCM) because of its easy to understand and implement. The another control method which is known as vector control method is the field oriented control method (FOC). Although FOC is more sophisticated than SCM, it is higher performance on control in general. In this study, the mathematical model of IM has used on simulation and FOC method has implemented on it. Then for speed control of IM Ziegler-Nichols method is used.Matlab/Simulink software has used to simulate system.
