Blade Pitch Control for Electrically Controlled Rotor Based on Online Identification of Error Path

DONG Weisheng, LU Yang(National Key Laboratory of Rotorcraft Aeromechanics,Nanjing University of Aeronautics and Astronautics,Nanjing 210016,China)  
In order to improve the control efficiency of blade pitch control of Electrically Controlled Rotor(ECR),two methods based on adaptive control method with online identification of error path,scaling factor method and constrained weight method,were proposed.According to the data collected from the open loop pitch control test and the least-squares method,mathematical model of control object was established.Then the ECR pitch control simulation work was conducted for the two proposed methods.Simulation results indicated that:1) the scaling factor method can effectively increase the speed of response and improve the control accuracy of both ECR collective pitch and cyclic pitch control,and keep itself adaptive;and 2) the constrained weight method can effectively restrain the interference caused by the external noise,and can improve the stability of the whole control system at the same time.
