Adaptive Control for Systems Subject to Magnitude Constraints and Stability Analysis
Speaker: Dr. Nazli E. Kahveci (USC)
Abstract
We consider the tracking performance of asymptotically stable systems with unknown parameters and input saturation constraints. An indirect adaptive control design with anti-windup augmentation is developed where the perturbation terms due to parameter errors do not destroy the stability properties of the system. We establish the boundedness of all signals in the closed-loop and maintain stability under saturation. Once the control input returns to its linear region, the adaptive control structure with the anti-windup compensator reduces to an adaptive controller where the input constraints can simply be ignored and thus the system response asymptotically tracks the external reference signal.
