| Abstract: | The control system of a simple wind tunnel is designed with an MSP430F149 single chip computer as the core component. The system measures the real-time height of the small ball using ultrasonic sensors, and produces PWM pulses controlled by the PID algorithm according to the error, which in turn control the speed of DC motor and keep the small ball moving stably, fast, and accurately on a predetermined trajectory. The system is an example of a modular design. It uses a separate keyboard as the input system, sets working mode, and uses LCD module as the output system to display real-time information of the ball＇s state. |
