In view of the instability,nonlinearity and tight coupling of three degrees of freedom helicopter system,a study on flight attitude control system of helicopter model has been done,with the use of fuzzy integration controller algorithm. Based on MATLAB simulation platform,a fuzzy integration control algorithm is studied for helicopter system,analyzed the robustness and anti-interference ability of the system,while comparing it with the traditional PID control algorithm. The result shows that the fuzzy integration control algorithm can effectively control the flight attitude of three degrees of freedom helicopter model,and has favorable dynamic quality,robustness and anti-interference ability.
