Abstract :
This paper proposes an adaptive control algorithm using multiple feedforward sensors and the wave propagation principle to eliminate noise in the downstream area of a duct. The algorithm is able to separate the dynamics of the sensor and actuator from the duct. Two experiments were conducted to show the effectiveness of the control law
