Abstract

The present paper is devoted to the modeling and the active suppression of brake squeal. Two different control strategies are described and tested on the basis of a four degree of freedom disk brake model. The first control law is based on optimal control and includes a filter to estimate the system’s state. The second law maximizes the energy dissipated by the friction forces between the disk and the brake pads. Both control strategies are compared with respect to their practical application and implemented in a floating caliper disk brake at a test rig.
