The application of FUZZY-PID control in constant temperature water bath

In biological engineering,medicine,food,chemical,metallurgy,oil and other areas of scientific research and production in the experimental conditions required constant temperature water bath.Temperature control have nonlinear,large delay and large inertia uncertainties.When deviation of PID control is large,the system vulnerable to integral saturation,resulting in the system greatly overshoot,or even out of control.Using the fuzzy PID complex control theory to temperature control,can effectively solve the shortcomings of water temperature control system to achieve satisfactory control effect.
