Application of Active Disturbance Rejection Control (ADRC) in the Radial Position Control of a Bearingless Induction Machine With Split Winding

In this work, the Active Disturbance Rejection Control (ADRC) technique was applied to control a simulated plant that represents the radial displacement of a bearingless induction machine with split winding. Active Disturbance Rejection Controllers have a robust operation when applied to systems with uncertainties, nonlinearities, and in the presence of disturbances. The work employed the linear and nonlinear versions of the ADRC to control the radial displacement. The simulations were performed in the Scilab software. The system response under parameter variation and external load are presented to compare the performance and implementation of both techniques.
