Intelligent control for refrigerating system of low-voltage and high-power ammonia compressor

Based on the principle of fuzzy control and neuron control, an intelligent controller is applied successfully to a system of low voltage and high power ammonia compressor. By regulating speed with an inverter, the power economizing technique for the system with constant torque load is realized. The real operating results show the robustness and superior dynamic performance of the system. It saves energy obviously and has great value to spread.
