Modeling and Simulation of Large Aircraft's Hybrid Control System

The research results in the field of modeling and simulation for large aircraft's hybrid control system is presented. After analyzing the control system structure of the aircraft's three axes, a method of treating flexible drive of the hybrid mechanism as a hard one is proposed. By means of equivalent dynamic modeling, a complete mathematics model of aircraft's aileron axis hybrid control system is established. Based on Matlab/Simulink software, an integral develop platform including modeling, design, hardware-in-the-loop simulation and handling qualities assessment is designed. The goal of this platform is low-cost, flexibility, extensibility and modularity. These aim is pursued by eliminating specialized hardware and software solutions and relying on commercial-off-the-shelf components.
