Abstract

This paper presents a design and implementation of Fuzzy Logic PID Controller using 8-bit microcontroller U-Board speed control. The speed of system depends on the speed of considered DC motor. So, the main speed control is to control the speed of considered DC motor. The completed system composes of Fuzzy PID controller, Half-bridge driver, motor, 4:1transmission gear, tire, and speed sensor. The controller reads the commanding speed from user and compares to the actual speed read by the speed sensor which is attached with the U-Board frame, performs the Fuzzy PID computation, then sets the result of calculation to the PWM ports to drive the motor. The tire of the U-Board is connected to the motor by the chain with 4:1 reduced gear, it can be clearly seen that the speed of U-Board is slower than the speed of motor 4 times. The feasibility and effectiveness of the control techniques are verified using the experimental results and implemented using the PIC 8-bit microcontroller under speed variation and showed the superiority of Fuzzy-PID.

模糊PID控制器采用8位单片机对u型板进行速度控制

本文提出了一种基于8位单片机u板速度控制的模糊逻辑PID控制器的设计与实现。系统的速度取决于所考虑的直流电机的速度。所以，转速控制主要是控制所考虑的直流电机的转速。完成的系统由模糊PID控制器、半桥驱动、电机、4:1传动齿轮、轮胎、速度传感器组成。控制器从用户处读取命令速度，并与u板框架上的速度传感器读取的实际速度进行比较，进行模糊PID计算，然后将计算结果设置到PWM端口驱动电机。u型板的轮胎通过链条以4:1减速齿轮连接到电机上，可以清楚地看到u型板的速度比电机的速度慢4倍。实验结果验证了控制技术的可行性和有效性，并在PIC 8位单片机上实现了变速控制，显示了模糊pid的优越性。
