基于ATmega16的变滚转速率飞行器姿态控制器设计

由于受横风、初始扰动和发动机参数偏差等因素的影响,变滚转速率飞行器在飞行过程中的飞行姿态将会发生变化,从而导致其实际飞行轨迹偏离预定飞行轨迹.本文利用AVR微控制器ATmega16及相应的信号调理电路,进行姿态控制器的设计,采用鉴频鉴幅方法对飞行器姿态角偏差进行处理,能够有效地修正飞行器姿态角偏差,完成对飞行器在变滚转速率飞行状态下的自适应姿态控制.

Attitude Controller Design on Variable Rolling Velocity Aerocraft Based on A Tmega 16

Owing to the effect of crosswind, initial disturbance and the deviation of engine parameters.etc in the initial aviation, vari able rolling velocity aerocraft will produce attitude angle deviation in the ideal orientations. This paper adopts AVR microcontroller atmega16 and relevant signal process circuit to design the attitude controller and take the method of frequency discrimination and amplitude discrimination to process attitude angle deviation of aerocraft. Accordingly, it amends attitude angle deviation of aerocraft effect and implements the self-adapting attitude control of aerocraft's rolling velocity.
