Suppressing chatter noise in windscreen wiper operation using a robust hybrid controller

It has become vital in the modern automotive industry to focus on the noise and vibration suppression of the vehicle sub-systems in order to maintain a competitive advantage. One of the vehicle sub-systems that very often to generate unwanted vibration and annoying noise is a windscreen wiper system. Windscreen wiper system, during its operation, causes a variety of noises such as chatter noise, reverse noise, motor and gear noise. This paper attempts to investigate and suppress chatter noise with frequency range of 50-150 Hz. In doing so, a robust controller design is proposed and integrated into a two dimensional analytical model of wiper blade system. A hybrid controller is comprised of IS shaping controller an effective feed forward controller and a proportional-integral-derivative (PID) controller. Particle swarm optimization (PSO) is further employed to enhance the capability of traditional techniques for vibration control and noise attenuation of windscreen wiper system.
