基于TMS320F28377D的微型舵机控制系统设计
|
摘要
利用TMS320F28377D双核CPU,实现了飞控和舵控集中在一个CPU,通过CPU1核与CPU2核之间内部信息共享区(IPC)实现信息交互,解决传统飞控计算机与舵控计算机需要通过外接通信接口实现通信的问题。舵系统采用片内AD采样设计,大大减少电源模块,其次实现了片内AD低电压状态下,舵反馈仍旧保持较高采样精度。最后通过仿真和实验论证该设计可靠性高,具有较强抗干扰性,工程价值较高,并能够实现舵系统微型化。
By using the TMS320F28377 D dual-core CPU, this thesis puts flight control and rudder control together in a CPU, and gets information interaction through internal information sharing area(IPC) between CPU1 core and CPU2 core. It solves the communication problem of traditional flight control computer and rudder control computer which was depended on the external interface in tradition. First of all, the steering gear adopts AD sampling design in the chip, which greatly reduces the power supply module. Secondly, the steering gear feedback keeps high sampling accuracy even the AD on the chip is under low voltage. Finally, it is proved that the design of the steering gear has characters of high reliability, strong anti-interference, high engineering value and miniaturization through simulation and experiment.
