The automatic intelligent control to the photoelectric color sorter available for granular material separation was realized by using the fuzzy PID strategy with automatic parameter identification. With the application of TMS320VC5402 as master controller to control the main sorting operation parameters including the sorting capacity, the background plate obliquity and the chute elevation according to the established fuzzy control rules, the automatic adjustment of the color sorter performance was achieved. Based on the fuzzy PID control, the intelligent control algorithm by DSP was implemented...
