Special Issue Information

Dear Colleagues,

This Special Issue is dedicated to presenting the latest advancements, innovative applications, and comprehensive research in actuator technologies that are pivotal for controlling and mitigating unwanted noise and vibrations across various sectors. The collection aims to provide a comprehensive overview of actuator technology’s current state and future prospects in active control systems.

Actuators are the dynamic workhorses of active noise and vibration control systems. They are responsible for generating the controlled counteracting forces or sound waves that nullify the negative effects of noise and vibrations. This Special Issue highlights the critical role of actuators, exploring their design, materials, and control strategies that enhance their performance in real-world applications.

The effectiveness of actuator technology is inextricably linked to the sophistication of the control systems that drive them. This collection of research papers delves into the latest in adaptive and intelligent control algorithms, exploring how these systems are becoming more responsive and efficient in managing complex and variable noise and vibration scenarios.

The active noise and vibration control field is inherently multidisciplinary, intersecting with acoustics, materials science, electrical engineering, and mechanical engineering. This Special Issue is a testament to the collaborative efforts of researchers across these disciplines, which drive forward collective knowledge and technological advancements in actuator technology.

To address the demand for low noise and high stealthiness in ships and other vessels, this paper innovatively proposes an inertial magnetic levitation actuator based on non-uniform-sized Halbach permanent magnet arrays. To improve control accuracy, it is necessary to establish an accurate analytical model of the magnetic field and then obtain an accurate electromagnetic force model. However, the distortion of the magnetic field at the ends produces end effects, resulting in thrust fluctuations that affect the actuator’s control accuracy. Therefore, considering the end effects is necessary to establish an accurate analytical model of the magnetic field. To analyze the end leakage magnetic field of the Halbach array, the concept of a mechanical pseudo-cycle in the actuator is proposed, and the cycle of a Fourier series is redefined. A completed analytical expression of the Halbach array magnetic field distribution is derived by the new Fourier series, in which the end leakage magnetic field is contained. The accuracy of the proposed method is verified by solving the analytical model of the magnetic field, and the analytical results are compared with finite element simulations and experimental tests.
