Research on fuzzy control technology ofDC motor in height automatic adjustingsystem of CNC cutting machine

Motor control technology is the key factor for height automatic adjusting system of CNC cutting machine.In this paper,one DC motor control technologis put forward based on the fuzzy control technolog andPWM control technology, and the fuzzy controller is designed as well. Experimental results show that the controlaccuracy and sensitivity of height automatic adjusting system will be improved by using the fuzzy control technologyand PWM control technology.
