In this paper, a variable step-size improved normalized subband adaptive filter (VSS-INSAF) algorithm is proposed, which addresses compromise between fast convergence speed and small steady-state error. The derivation of the time-varying for each based on reasonable technique, that is, letting powers system noises equal those posterior error signal. Besides, proposed VSS-INSAF uses noise estimate method. Simulation results present excellent performance when compared with existing algorithm.
In this paper, by inserting the logarithm cost function of normalized subband adaptive filter algorithm with step-size scaler (SSS-NSAF) into sigmoid structure, proposed sigmoid-function-based SSS-NSAF yields improved robustness against impulsive interferences and lower steady-state error. order to identify sparse impulse response further, a series sparsity-aware algorithms, including L0 norm constraint (SL0-SSS-NSAF), proportionate NSAF (S-SSS-IPNSAF), (SL0-SSS-IPNSAF), is derived structure...
The stability analysis and controller design problems for the fractional-order (FO) direct-drive permanent magnet synchronous generator (FOD-PMSG) wind turbine with parameter uncertainties external disturbance are addressed. Takagi–Sugeno (T-S) model is used to approximate nonlinearities, parallel distributed compensation (PDC) technique employed construct fuzzy state feedback controller. In order suppress more effectively, global Mittag-Leffler definition satisfying H∞ performance index...
