Abstract

A digital-analog hybrid control method is proposed to improve the performance of traditional analog adaptive interference cancellation system (AICS). The system model with digital proportion control was built. The stability condition and the interference cancellation ratio (ICR) were obtained. The convergence time was analyzed in detail, and it is found that there is the only optimal step size μ, set by the digital controller, that can make the system converge fastest. The experimental results are in agreement with the theoretical analysis.
