✦ Synopsis
The optimization problem of adaptive stochastic terminal control systems accommodating to changing disturbance characteristics is considered. It is assumed that a plant with randomly changing or fixed structure is operated under non-Gaussian disturbances described by non-linear models. Direct information about random structural changes of the disturbance model is absent. For systems with various types of structural changes the optimal adaptive terminal control laws are obtained in analytical form. Filtering-prediction-recognition algorithms are designed for realization of these control laws. It is found that the synthesized regulators provide a disturbance accommodation control strategy with adaptation to structural changes of the disturbance model. A principal difference from traditional control laws is illustrated by simulation studies.
