On the efficiency of adaptive control systems of nonlinear control object with the uncertainties and incomplete measuring

Implementation issues of direct adaptive control system of nonlinear nonstationary objects with uncertain descriptions are considered. Simultaneously the control object is not fully measured. It is proved that the exponential dissipation, i.e. the final adaptation process boundedness, can be ensured. Estimates of accuracy and speed of convergence between adaptee and reference model trajectories are given in detail.
