Abstract: This paper discusses the tracking of the desired poles by designing a state feedback controller and observer using Singular Value Decomposition method of pole placement for time varying systems. As the fluxes are taken as state variables, the measurement of these variables might become tedious in some cases. Hence, the state variables are fed back to realize control over the system. The accuracy of the values obtained from the controller may not be precise owing to the price, placing and disturbances induced by sensors. Hence an observer comes in handy and the characteristics for different torque conditions are observed.
