Adaptive Stabilization of Systems with Parametric Uncertainty on the Basis of Localization Principle

摘要

The adaptive stabilization problem for systems with nonstationary objects is discussed. The nonstationary characteristics of controlled object result from parametric and (or) limited additive disturbances. The desired transient processes are formed by a slow output variable and processes in fast movements subsystem are stabilized. The synthesis of the full and lowered order adapters as well as convergence conditions of the output processes of the system to a desired trajectory are considered. It is shown that due to "fast" adaptive algorithm it is possible to provide the prescribed dynamic accuracy of the system.
