Numerical Simulation and Experimental Study of Fuzzy-PID Control Method for Liquid Nitrogen Direct Evaporation Refrigeration System

Numerical Simulation and Experimental Study of Fuzzy-PID Control Method for Liquid Nitrogen Direct Evaporation Refrigeration System

More presetting tasks for parameters in traditional PID controlling are required, thereby leading to complex processes, unsatisfied control effects, and poor adoption for system condition changing. In the liquid nitrogen direct evaporation refrigeration system, a fuzzy-PID control strategy was propo...
