摘要
Convergence of the forgetting factor least square algorithm (FFLS) is analyzed by using stochastic process theory; and the upper bound of the parameter estimation error is derived. For timevarying stochastic systems, the FFLS algorithm is capable of tracking the time-varying parameters and the parameter estimation error is bounded. The upper bound of the parameter estimation error can be minimized by choosing the forgetting factor properly. Simulated results obtained support the theoretical findings.
