| Digital control speed regulation system is more and more used in undergraduate experimental teaching because of its short development cycle and open characteristic of controller. The experiment of dc speed regulation system based on data acquisition card is developed. The data acquisition card NI usb-6008 is used to transmit the speed and current signals to the upper computer without modifying the traditional simulation experimental equipment. The upper computer outputs the phase shift control voltage which control motor drive circuit, realizes the data communication and control between the upper computer and the actual hardware system. The control program was written in MATLAB/Simulink environment to form a visual control interface and facilitate the modification of program and controller parameters. This paper describes the overall design of the experimental system, and gives a complete control program block diagram. The experimental results verify the effectiveness and feasibility of the control strategy of the experimental system |
