Design and Implementation of Space Flight Control System Based on PD Control

摘要:

当前的飞行器控制系统在运行过程中容易受到噪声因素的干扰,对飞行器的控制存在滞后性和片面性,无法直观描述飞行器的运行状态,设计并实现了一种抗干扰能力强的航天飞行器控制系统,给出了无刷直流电机、电源电路、无线通信模块以及RS-232接口的硬件设计原理,给出了系统主控中心的人机交互界面组成；通过PD算法运算出不同电机的调整量,按照运算出的调整量控制电机的PCA模块,进而控制飞行器电机的转速,调整飞行器的姿态,克服干扰；实验结果说明,该种系统可对飞行器的各种飞行攻角进行准确的控制,该种系统的控制效率参数优于传统系统。

Abstract:

Current aircraft control system in the process of running vulnerable to the interference of noise factors, control of the vehicle delay and one-sided, cannot intuitionistic description vehicle running status. Designs and realizes a kind of strong anti-jamming capability of a new generation of aircraft control system, and gives the brushless dc motor, power circuit, wireless communication module and the hardware design principle of RS - 232 interface, gives the system master control center of human-computer interaction interface. Through the PD algorithm operation adjustment quantity of the different motor, the quantity of adjustment according to the operation control of the motor PCA module,, in turn, control the turning speed of the vehicle motor, adjust the attitude of the aircraft, the interference is restrained. Experiment result shows that this system can accurately control aircraft flight Angle of attack, the control efficiency of this kind of system parameters is superior to the traditional system
