Content of main publications:

  1. A.K. Belyaev, V.A. Polyanskiy, N.A. Smirnova, A.V. Fedotov, Identification procedure in the modal control of a distributed elastic system, St. Petersburg Polytechnical State University Journal. Physics and Mathematics. 10(2) (2017) 69–81: The article is devoted to the problems of implementing the modal approach to the control of distributed elastic objects - an experimental identification procedure is proposed which allows one to configure the loops of the modal control system.
  2. Belyaev A.K., Fedotov A.V., Irschik H., Nader M., Polyanskiy V.A., Smirnova N.A. Experimental study of local and modal approaches to active vibration control of elastic systems // Structural Control and Health Monitoring. 2018. V. 25. №2. e2105: The article describes an experimental study on the implementation and comparison of the efficiency of local and modal approaches to suppression of forced resonance vibrations of elastic objects on the example of a metal beam with elastic fixation. It is shown that the modal approach to control is more efficient than the local one in cases where it is necessary to suppress forced vibrations simultaneously at several resonance frequencies of the object.
  3. Fedotov A.V. Active vibration suppression of Bernoulli-Euler beam: experiment and numerical simulation // Cybernetics and Physics. 2019. V. 8. № 4. P. 228-234: The article proposes an effective method for numerical simulation of the results of an experiment conducted earlier by the author on suppression of vibrations of a Bernoulli-Euler beam within the framework of local and modal approaches. The results of the proposed numerical method are in good agreement with the experiment, which allows the author to design numerically a new modal control system, which is significantly more efficient than all the systems created in the framework of the experiment.

(eds) Dynamics and Control of Advanced Structures and Machines. 2019. Springer, Cham. – P. 127-135: The article numerically investigates the applicability of a simplified approach to modeling the joint operation of a control object (metal beam) and control elements (piezoelectric sensors and actuators), the main feature of which is the neglecting of the influence of piezoelectric elements on the vibration modes of the object. It is shown that this simplification of the system model leads to a significant decrease in the efficiency of control systems designed using this model, which are used to suppress forced resonance vibrations of the beam.
  5. Fedotov A.V., Belyaev A.K., Polyanskiy V.A., Smirnova N.A. (2022). Local, Modal and Shape Control Strategies for Active Vibration Suppression of Elastic Systems: Experiment and Numerical Simulation. In: Polyanskiy, V.A., Belyaev, A.K. (eds) Mechanics and Control of Solids and Structures. Advanced Structured Materials, vol 164. P. 151-169. Springer, Cham: The article gives a joint review of the experimental and numerical results obtained by the authors of the application of three different approaches (local, modal and shape control) to suppression of forced resonance vibrations of distributed elastic systems on the example of a metal beam. It is shown that if it is necessary to suppress forced bending vibrations of the beam only at the first resonance, the shape control method gives the best result, while if it is necessary to work simultaneously at several resonances, the most preferable is the modal approach.
