Popis:	This paper describes recursive maximum likelihood (RML) algorithm for tracking the sinusoidal frequency. The algorithm is modeled and simulated using Matlab/Simulink software package. This paper describes how to adjust the algorithmic parameters to estimate the frequency with high accuracy in steady state and also for tracking rapidly changing frequency. The measurement bandwidth of at least 10 Hz can be achieved with an update time of 500 /spl mu/s. It is suitable for real time operation since there are only 13 multiplications, 13 addition and 1 division in each iteration. Practically it needs only 11 /spl mu/s per update on a TMSC32 processor.
