【Abstract】 Due to the inability to set up an exact mathe-matical model of water cooling system which is caused by the nonlinear characteristics of strong couplings, distribution parameters, and their time-varia- tion, the fuzzy control strategy is employed to control the flow of cooling water, so that the coolant tem- perature is kept to be constant as required by the measurement system during the experimental process. It is verified by means of simulation that a better controlling effect can be achieved.更多还原
