【Abstract】 In view of the present electric curtain control system for the lack of control accuracy, instability of the system error, a fuzzy self-tuning PID control algorithm was proposed and used in the system control. The system took CC2530 as the core of communications and control, which was embedded in the fuzzy PID control algorithm. The users’ requirements could be responded quickly and accurately. Eventually it could control the curtain under the users’ command and complete the manually smart control to the desired degree. After a system simulation test, the output of the system was not up to the overshoot and it acquired the setting time of 0.18 s and steady-state error of about 0.15%, which were less than the conventional PID control. Thus it has certain practical and theoretical research reference value.更多还原
