Design and Simulation of a Kind of Unmanned Helicopter Fixed-Altitude Flight Control System

摘要

In order to improve the stability and the rapidity of Fixed-Altitude unmanned helicopter flight control system, this paper improves the control performance of the closed-loop system by establishing the dynamic mathematical model of unmanned helicopter and adjusts the parameters of the controller under guidance, and completes the simulation with MATLAB. Through the performance evaluation and series, feedback correction, and improved system performance, a quality improvement of unmanned helicopter Fixed-Altitude flight is obtained. This method can reduce the modeling workload and difficulty effectively, and express the process of unmanned helicopter Fixed-Altitude flight intuitively.
