A Comparative Study Based on Different Control Algorithms for Suppressing Multistage Gear Transmission System Vibrations

Abstract

A modal analysis (MA) was preconsidered to determine a novel active vibration control (AVC) structure of multistage gear transmission system (MGTS) and an appropriate actuating position for the piezoelectric actuator (PZT); the results of the calculating method and the finite element method (FEM) were compared to validate the reliability of MA. The controllers based on different control algorithms were designed to drive the PZTs to output the control force for suppressing the host structure vibrations. To analyze the feasibility of the applied control schemes and discuss the control effects dominated by the different control algorithms, a series of active vibration control numerical simulations were studied. The cosimulation results validate the practicability of the proposed control schemes and provide a forcible guidance for the further experimental works.

“…Gao et al [10] presented vibration control of an internal shaft to reduce gear mesh vibration using a modified Fx-LMS control algorithm. Also, in order to suppress the vibrations of multistage gear transmission systems, Sun et al [11,12] proposed an active vibration control using piezoelectric actuators acting on the transmission shaft. PID, fuzzy and Fx-LMS algorithms were used to control the fundamental and harmonic vibrations.…”

Reducing instabilities of mesh stiffness variation in two-stage gear using phasing method

“…Results from the experiment showed that there was a signifcant decrease in vibration within the the gearbox housing and the noise levels of gear whine at the first and second frequencies of the operating gear mesh. A different comparative study [4] that was centered on dissimilar control algorithms for reducing vibrations of multistage gear transmission system was carried out. The different control algorthims were used to design controllers that drove the actuators that are responsible for regulating the force that reduces vibrations of the host structure.…”
