摘要
针对无人机的特殊性以及对电机动态性能的要求,设计了一种以ARM芯片LPC2148为核心的旋翼转速控制器。首先分析了直升机的飞行特点以及原旋翼转速控制器的不足,设计基于EKF和矢量控制的新旋翼转速控制器,并对扩展卡尔曼滤波法和矢量控制的模块进行说明,且给出了MATLAB仿真结果,验证了控制系统的正确性。
Concerning the specificity of UAV and the dynamic performance of motor,a rotor speed control system using ARM chip LPC2148 as the center is designed. The flying characteristics of helicopter and the deficiency of traditional rotor speed controller is introduced at first,and then describes new rotor speed controller based on extended Kalman filter and vector control method and the illustration of EKF as well as the modules of vector control system.Simulation results of Matlab also verify the correctness of the control system.
