Research and Design of Motor Control System Based on Labview PCI

Using virtual technology (labview) to study and design a kind of system software to detect and control DC motor. Functions include three parts: detection and analysis of motor speed frequency, forward and reverse rotation detection of motor and PID speed control. Using Alta PCI8932 signal acquisition card as a virtual software data input and output platform. Using labview software for interface and program design, mainly related to user interface design, data input and output design, speed detection design, motor forward and reverse rotation detection design and PID control design. Through the non-contact detection method, the motor speed detection and control can be realized.
