A Novel LS-SVM Generalized Inverse Control of Three-phase Active Power Filter Based on Improved Adaptive Harmonic Detection
Aiming at the problem that the traditional control has a limited control bandwidth and delays in digital implementation, a novel generalized inverse control of three-phase active power filter is studied in this paper. And the generalized inverse system can be approximated by LS-SVM due to the fast operational speed of LS-SVM. On the other hand, since the traditional algorithm has slow convergence rate and that the adaptive method with LPF has the drawback of slow dynamic response; an improved adaptive method for harmonic detecting based on integrated mean value is researched in this paper. .In order to have a good linearization control effect, the generalized pseudolinear system can be obtained by internal model and the generalized inverse system. At last, the simulation results show that a good steady-state performance and a rapid transient response can be obtained under the unproved method.
