摘　　要：为实时修正制导炸弹弹道轨迹从而精确命中目标,设计一种简易制导炸弹舵机控制系统。该系统硬件部分以ds PIC33EP512MC806为控制核心、以PWM信号驱动用H桥芯片BTS7970B控制直流电机、以外扩A/D采集芯片TLC2374采集经电位器测量的舵面位置反馈信号;软件采用C语言实现5个模块之间的通信。分析结果表明:该系统简化了电路设计的难度,提高了可靠性,满足了制导炸弹的性能要求。A simple guide bomb＇s servos control system is designed aiming at revising ballistic trajectory of guide bombs in real time to hit targets precisely. The hardware part used dsPIC33EP512MC806 as control core, PWM as drive, H-bridge chip BTS7970B to control DC electric motor, extended outside A/D acquisition chip TLC2374 to acquire feedback signal of control surface position which is measured by potentiometer. Communication between five modules is achieved by using C language. The test shows that the difficulty of circuit design is simplified, and the reliability is improved. This system can meet performance requirement of guide bomb.
