Improved Algorithm Simulation of Adaptive Blade Pitch Control for Electrically Controlled Rotor

Abstract

Based on the former adaptive blade pitch control method of the Electrically Controlled Rotor in time domain, two improved control algorithms are proposed. One method is through adding a weight-constrained function for active control filter, which can prevent the divergent of control system caused by interference signal of error channel. The other method is through adding a desired signal of scaling factor to replace the identification process of the forward path. The algorithm can enhance the real time characteristics and the response characteristics of control system. In addition, the comparison between two improved methods and the former method is conducted, and the simulation analysis is made based on the matlab/simulink. The simulation results show that the two proposed methods have better system robustness, and the control characteristics are obviously superior to the former system.
