- This paper develops an active control algorithm for a system with nonlinear damper. Since the system is nonlinear, the response depends on the level of excitation. Conventional adaptive algorithms with a linear model of the plant may not converge or can be very slow. Therefore, a level dependent model of the plant is used to control the vibration. The adaptive controller converges more quickly than a linear fixed plant. This controller has been applied in the ACSR system used in helicopters to control the vibrations transmitted to the airframe from the blade passing frequency.
