DC Motor Speed Control using Labview FPGA

This paper represents more reliable FPGA hardware implementation of dc motor speed control system. In this a control design & simulation module is used to simulate both DC motor model & its control system. Also it can simulate the FPGA clock timings. Novel Hardware & software co-design approach for design of PID control algorithm, stimulus (PWM) generator, feedback sensor (Quadrature encoder) interface is presented. Flexible FPGA module allows easily reuse of code used in development process during actual hardware implementation. Unlike conventional hardware designing which requires VHDL expertise, the developer need not to know in-between processes of ready to download final bit-file generation. Finally the bit file will be downloaded in CompactRIO-9076 (reconfigurable platform) assembled with C series analog & digital I/O modules which interact with signal from DC motor plant.
