【Abstract】 In order to solve the problem of getting the reference signal and the nonlinear system, the IMC structure and neural network are adopted. The IMC-neural network controller is designed to suppress the noise. Computer simulations and experiments show that this control structure can reduce tonal frequency noise effectively. A nonlinear example is given to support that the IMC-neural network control method is more efficient to the nonlinear noise control than the Filtered-x LMS algorithm.更多还原
