Design and realization of fuzzy self-tuning PID speed controller based on TMS320F2812 DSPs

This paper discussed how we should apply fuzzy self-tuning PID controller to AC-speed adjustable system, and emphasized how to realize this controller using fuzzy search table method in C++ language based on TMS320F2812, which is the newest 32-bit fixed point DSP from TI company. The author eventually applied this controller to PMSM-speed adjustable vector control system in MCK2812, which is a motion control development kit of technosoft company. And the results show that this controller can improve dynamic characteristics and static characteristics of system obviously.
