Abstract:

Aiming at ac motor closed-loop control difficult, a frequency conversion system was designed base on PLC and fuzzy algorithm. This paper deals with a PLC and frequency converter controle AC induction motor method, as well as constructed two-dimensional fuzzy controller by PLC, realize the dynamic control of nonlinear systems, avoiding the complexity of modeling, improve the system stability and anti-jamming capability. On-site testing shows that this system has a high intelligence and better robustness, can frequency control of motor speed accurately.
