This study aims to design and manufacture a digital PID controller kit integrated on a MCU-MSP430 of the Texas Instruments Inc., which allows collecting real time data and transmittinging to a PC. A low power DC motor is used as a control plant to verify the performance of proposed controller kit and computer infterface software. Experimental results show that the ability to integrate the digital PID controller on the MCU-MSP430 is feasible; the PC interface tool can conveniently display and record the transient system response.
