“…With the rapid development of sensing technology, more online identification and self-adaptive control algorithms are investigated in developing the active vibration control in precision milling. Zhang et al [18]constructed a novel hybrid error criterion-based frequency-domain least mean squares ( LMS ) active control method to improve the adaptability, reliability and anti-interference ability of the control algorithm. The selection of linear feedback rate [19] can be adopted to improve the robustness and capacity to resist disturbance of systems.…”

The tool-workpiece vibration in the precision milling process plays a pivotal role in influencing the surface quality. To solve the machining problem coming with the process vibration, the active vibration control model as well as the corresponding platform are developed, and the active vibration control algorithms are applied to reduce the relative vibrations and improve the surface quality. Firstly, the milling vibration reduction and surface quality improvement are modelled based on the active control algorithms and the system dynamic characteristics. Then, applying the different algorithm control strategies, such as PID, Fuzzy PID, BP neural network and BP neural network PID control, the control effect is simulated and analyzed. Finally, the platform is experimentally set up to verify the reliability of the system, the frequency vibration control and the finish surface roughness improve efficiency of different active control methods are compared, providing optimal vibration control methods for precision milling.

“…Given the constraints imposed by the suggested application (which may also be present in others), the hardware of the control system needs to be selected with the total mass kept to a minimum. Piezoelectric elements are renowned within vibration control due to their relatively high force output to mass ratio, and they have been previously used as sensors [2,3], actuators [4,5], and self-sensing actuators [6][7][8]. They have also been used in different categories of vibration control as in passive [9][10][11], semi-passive [12,13], and active [14][15][16].…”

The linear control of a nonlinear response is investigated in this paper, and a nonlinear model of the system is developed and validated. The design of the control system has been constrained based on a suggested application, wherein mass and expense are parameters to be kept to a minimum. Through these restrictions, the array of potential applications for the control system is widened. The structure is envisioned as a robot manipulator link, and the control system utilises piezoelectric elements as both sensors and actuators. A nonlinear response is induced in the structure, and the control system is employed to attenuate these vibrations which would be considered a nuisance in practical applications. The nonlinear model is developed based on Euler–Bernoulli beam theory, where unknown parameters are obtained through optimisation based on a comparison with experimentally obtained data. This updated nonlinear model is then compared with the experimental results as a method of empirical validation. This research offers both a solution to unwanted nonlinear vibrations in a system, where weight and cost are driving design factors, and a method to model the response of a flexible link under conditions which yield a nonlinear response.

Active balancing actuators are essential components of intelligent machine tool spindles to automatically reduce the unbalance vibration and promote machining accuracy and efficiency. In this study, a novel electromagnetic-ring actuator is introduced, which can be integrated into the hollow rotor of the spindle and compensate the initial mass imbalance through step rotation of two counterweight discs driven by the magnetic field. The working principle of the actuator is described in detail and its performance is analyzed, including balancing ability, balancing accuracy and self-lock capacity. To control the normal operation of the actuator, a phase detection and control program was developed. Finally, to verify the effectiveness of the novel actuator, function experiments and active balancing experiments were carried out. The experimental results show that the novel actuator could reduce the unbalance vibration of the machine tool spindle by 87.5% at 3600 rpm.
