   Indirect model reference adaptive control of cascade systems based on the speed-bigradient method / Nguyen C . T., Finoshin A. V. // Мехатроника, автоматизация, управление. - 2025. - Т. 26, № 4. - С. 167-177.

The adaptive tracking control problem for the linear cascade system consisting of two subsystems is considered. The modification of the Speed bi-gradient method is proposed to improve both the accuracy and the robust property. The considered modification is performed by an extending the dimension of the output subsystem of a cascade system, and forming the information output as the generalized tracking error dynamics, and the virtual control synthesis as the local feedback of an information output. The four-stage design procedure of the indirect adaptive control is proposed. The achievement of the tracking control objective is proved by a Lyapunov method. The finite-time stability of the sliding manifold and the information output is ensured. Identification properties of a control law are investigated. Both the control law design and simulation results for the third order cascade control plant are presented.
