Dilution valve are the most important equipment of dilution water headbox,in order to solve the problems of the con-trol,a new type of circuit board were developed.Which use the MCU’s multifunction port of PWMgenerates the high-speed pulse signal to control the stepper motor drive chips,via the multifunction port of analog to collect the valve position.A new method which use the acceleration-deceleration arithmetic and programs were proposed to improve the valve’s accuracy,the total error of dilution actuator were less than 2.8% in one thousandth step length,and at least have more than 1000 steps credible accuracy.
