摘　　要：无人机锂电池的特性与环境温度紧密相关。低温时锂电池的放电周期迅速降低;高温时电池放电周期变化很小。设计了一种基于LM35A和单片机PID调节的温度控制系统,系统以ATmega128单片机为核心,通过LM35A采集电池温度,以电池表贴电阻片为控制对象,采用数字PID调节实现电池温度的控制。根据实验数据分析,本系统使电池在工作温度范围内具有良好的放电状态,从而证明本设计合理且实用性强。The lithium battedes characteristics of UAV （unmanned aedal vehicles） are closely related with the environmental temperature. The discharge cycle of lithium battery rapidly reduces at low temperature, but it lightly changes at high temperature. A temperature control system based on the LM35A and the microcontroller PID regulator was designed by using ATmega128 microcontroller as the core, collecting battery temperature through LM35A, taking SMD resistor as control object and controlling battery temperature by digital PID regulator. According to the analysis of experimental data, the system makes the battery in the operating temperature range have a good state of discharging, proving the rationality and practicability of the design.
