An active control method to reduce the effect of negative damping in disk brake system
In this paper, a novel approach to reduce the effect of negative damping that causes brake noise is proposed by applying an Active Force Control (AFC) based strategy to a two degree-of-freedom model of a disk brake system. At first, the disc brake model is simulated and analyzed using a closed loop...

| Summary: | In this paper, a novel approach to reduce the effect of negative damping that causes brake noise is proposed by applying an Active Force Control (AFC) based strategy to a two degree-of-freedom model of a disk brake system. At first, the disc brake model is simulated and analyzed using a closed loop pure PID controller. Later, it is integrated with AFC and simulated under similar operating environment. After running several tests with different sets of operating and loading conditions, the results both in time and frequency domains show that the PID controller with AFC is much more effective in reducing the vibration and noise, compared to the pure PID controller alone.
