Adaptive Control as a Hierarchical System

An adaptive control system is a system that can cope with variations in a plant where it plays a major role in smart controllers needed for sophisticated systems. In this study, the adaptive control system is represented as a hierarchical control structure consisting of primary, secondary, and supervisory levels to monitor the system performance and adjust controller parameters for system regulation and stability. To validate the adaptive control concept, a basic automatic voltage regulator model is employed as an example. System performance is assessed against the conventional feedback control system under different step perturbations. The results demonstrate the effectiveness of the proposed adaptation mechanism, acting as a secondary control loop, in achieving superior performance and stability compared to the conventional one.
