基于自适应模糊PID的电动车手套控温保暖系统

Temperature control and warming system based on adaptive fuzzy PID for electric vehicle gloves

针对电动车保暖手套在电动车行车过程中受到行驶速度、气温、风速等非线性因素的影响,传统PID的控制参数无法自适应调节,难以满足电动车手套对温度自适应调节的需求,提出了一种基于自适应模糊PID控制的电动车手套控温保暖系统。根据模糊规则对电动车手套实际温度与设定温度之间的误差和误差变化率进行模糊推理,得到系统控制参数Kp、Ki、Kd的增量ΔKp、ΔKi、ΔKd,从而进一步调整Kp、Ki、Kd,以满足不同环境下手套对温度自适应调节的需求。该系统采用STM32F103C8T6单片机、语音识别播报模块、人体感应模块等进行硬件设计、软件开发和实验验证,结果表明:该系统相比传统PID控制显著提高了电动车手套对温度控制的精度,且系统超调量少、鲁棒性强,对提高不同环境下的实时温控系统的可靠性和提升电动车手套的穿戴舒适性具有重要意义。

In the influence of driving speed,air temperature,wind speed and other nonlinear factors during driving,the traditional PID,with poor ability to adjust adaptively temperature,is difficult to meet the needs of selfadaptive temperature adjustment about the electric vehicle gloves.So a temperature control and thermal insulation system based on adaptive fuzzy PID for electric vehicle gloves is designed.According to the fuzzy rule,the error and the rate of error change between the actual temperature and the set value of gloves are deduced.The incrementΔKp,ΔKi,ΔKd of Kp,Ki,Kd are obtained,then the PID control parameter Kp,Ki,Kd can be further adjusted to meet the needs of adaptive adjusting gloves temperature in different environments.The system adopts STM32F103C8T6 micro controller,voice recognition and player module,human body induction module and other sensors for hardware design,software design and experimental verification.Experimental result shows that compared with traditional PID control system,the new design significantly improves the temperature control accuracy of electric vehicle gloves,with less overshoot and stronger robustness.It is great significance to improve the reliability of the real-time temperature control system in different environments and the comfortable sensation of wearing electric vehicle gloves.
