An Efficient Adaptive Direct Frequency Estimation Algorithm Using A Constrained IR Notch Filter with Guaranteed Stability

A new adaptive algorithm for direct frequency estimation is developed using a constrained IIR notch filter. The basic characteristics of this proposed algorithm are that the computational cost is very low and that the stability of the adaptive IIR notch filter can be guaranteed by a normal state-space realization. These features make the proposed adaptive algorithm both efficient and robust
