针对被控对象存在的大惯性、纯滞后的特点,采用了模糊控制方式的控制策略,设计了一种高精度温度控制算法，并以STC89C52单片机为核心, 以及测温元件、转换电路等构成闭环温度控制系统。(object against the great inertia, pure hysteresis characteristics, fuzzy control the control strategy, design a high-precision temperature control algorithm, and STC89C52 microcontroller core, and the temperature components, conversion circuits comprise a closed-loop temperature control system.)

STM32F407，2016年电子设计大赛D题，实现SPWM逆变电源(STM32 implementation of SPWM)

全自动可遥控旗帜升降系统以AVR单片机为核心，由PWM对电机进行变频调速，高精度光电编码器测速，闭环式电路控制。能够利用按键输入相应的指令控制旗帜的升降，还可以实现在特定位置停留的功能。利用LCD可以显示旗帜的实时高度和相应的控制命令，用LED指示旗帜是否处于半旗状态，具有语音提示报警功能，并可利用无线模块实现遥控功能，准确均匀地实现旗帜的升降(Automatic landing system can be remote-controlled flag to AVR microcontroller core of the PWM VVVF motor, high-precision optical encoder gun, closed-loop control circuit. Enter the appropriate button to take advantage of the command control of the rise and fall of the flag, but also can stay in the function of a specific location. LCD can display the banner of the use of real-time high and the corresponding control command, the LED is directed at the flag half-mast, and alarm functions with voice prompts, and the use of wireless remote control function module, to achieve uniform and accurate take-off and landing flag)
