Design of Airborne Pod Control System Based on STM32

摘要:

机载吊舱控制系统要求对俯仰和方位两个自由度进行控制,通过光电编码器进行信息反馈,以此构成闭环系统,对控制精度和抗干扰能力有严格要求；提出了一种基于STM32的机载吊舱控制系统的设计方案,并在STM32平台上进行μC/OS-II嵌入式系统移植,同时加入PID控制算法用来提高系统的控制精度和抗扰动能力,结合控制需求,开发了机载吊舱的两自由度控制程序,实现了上位机控制命令的传输和伺服控制单元的信息反馈,最后通过实验验证设计结果；该控制系统软硬件裁剪方便、控制精度高,对吊舱控制系统的开发应用具有一定的参考意义。

Abstract:

Airborne pod control system requirements for pitch and azimuth control of two degrees of freedom, through the photoelectric encoder feedback, this closed loop system, control accuracy and anti-jamming capability, there are strict requirements. This paper presents a STM32-based airborne pod control system design, and transplant the μC/OS-II embedded system on the STM32 platform, While adding PID control algorithm is used to improve the control precision of the system and the anti-disturbance capacity, combined with the control requirements, developed two degree freedom control program of airborne pod, realized the upper computer control commands transmission and feedback the information of the servo control unit. Finally, through experimental results validate the design. The control system hardware and software tailored convenient, high control precision,It has certain referential meaning to the development and application of the control system of pod.
