Special Issue Information

Dear colleagues,

Oscillations manifest in numerous dynamic systems. Vibrations can be found in a wide range of applications of mechanical, electric, electronic, electromechanical, and electromagnetic systems. Actuators constitute an important component of successfully accomplishing vibration control in addition to parametric estimation on vibrating engineering systems.

This Special Issue aims to present recent and innovative contributions on vibration analysis, system identification, estimation of parameters and signals, and diverse control methods for a wide variety of oscillating systems. Important advances on both theoretical and experimental studies for analysis, identification, and control of oscillating systems, including the application of actuators, are within the scope of the present Special Issue.

Thus, in this context, we welcome important contributions related (but not limited) to modeling, vibration control, estimation and identification, vehicle suspensions, dynamic vibration absorbers, rotordynamics, wind energy conversion systems, modal analysis, dynamic structures, finite element analysis, numerical methods, and other engineering applications and theoretical developments on this very broad matter.

Interval Analysis of the Eigenvalues of Closed-Loop Control Systems with Uncertain Parameters

Uncertainty caused by a parameter measurement error or a model error causes difficulties for the implementation of the control method. Experts can divide the uncertain system into a definite part and an uncertain part and solve each part using various methods. Two uncertainty problems of the control system arise: problem A for the definite part—how does one find out the optimal number and position of actuators when the actuating force of an actuator is smaller than the control force? Problem B for the uncertain part—how does one evaluate the effect of uncertainty on the eigenvalues of a closed-loop control system? This paper utilizes an interval to express the uncertain parameters and converts the control system into a definite part and an uncertain part using interval theory. The interval state matrix is constructed by physical parameters of the system for the definite part of the control system. For Problem A, the paper finds out the singular value element sensitivity of the modal control matrix and reorders the optimal location of the actuators. Then, the paper calculates the state feedback gain matrix for a single actuator using the receptance method of pole assignment and optimizes the number and position of the actuators using the recursive design method. For Problem B, which concerns the robustness of closed-loop systems, the paper obtains the effects of uncertain parameters on the real and imaginary parts of the eigenvalues of a closed-loop system using the matrix perturbation theory and interval expansion theory. Finally, a numerical example illustrates the recursive design method to optimize the number and location of actuators and it also shows that the change rate of eigenvalues increases with the increase in uncertainty.
