Based on the fuzzy PID brushless DC motor control system design

This paper according to the traditional PID control system of the nonlinear time-varying, is not easy to realize the on-line adjustment of the flaw and proposed one kind based on the FPGA (Field Programmable Gate Array), implementation of fuzzy PID control algorithm and its application to brushless DC motor speed control system. Using VHDL (Very High Speed Integrated Circuit HardwareDescription Language) language and Quartus II built-in macro module on the PID modules are constructed. In the construction of the PID module based on fuzzy control theory to join. The application of Matlab system simulation tools and Quartus II waveform simulator to construct fuzzy PID module simulation, and the application of fuzzy PID module on brushless DC motor speed control, then make whole speed control system is more reliable. The simulation results show that: based on FPGA realizing fuzzy PID control system has the advantages of simple structure, easy modification and can make the system reach the speed more stable results.
