Research on Single Channel Rolling Control for Fixed Canard Rudder

Abstract

According to the rotate speed switching problems of rapidity and stability during single channel rolling control for fixed canard rudder, the control algorithm based on active disturbance rejection controller (ADRC) was presented to control the rudders rotate speed switching. The working principle of fixed canard rudder was analyzed, and the mathematical model of the rudder was established, and the ADRC cascade controller for the rudder was designed. The simulation results indicates that not only the proposed rotate speed switching control strategy for the rudder is feasible, but also the proposed ADRC algorithm improves the rapidity of speed switching process, with switching time of 30ms, no overshoot, and very good robustness under inner perturbation and external disturbance with nonlinear friction considered.
