Study on Surface Nitriding Current Control for Steel Based on Fuzzy PID
A fuzzy PID controller used to control nitriding current for steel surface was designed through fuzzy PID controller and PID controller.The effects of fuzzy PID controller were also studied.The results show that compared with traditional PID controller,the fuzzy PID controller has better control precision and stability,which can adjust time at 7 s and overshoot for 15 mL.
