| Abstract:Considering high price of imported and low accuraly and integration of domestic products of cross direction basis weight actuator of dilution water headbox, a new type of circuit board integrated controller was developed. In order to improve the accuracy of valve, using S-curve of speed to treat the lose step and overshoot of the drive element. The controller used the MCUs four-channel multifunction high-speed pulse port controlled the stepper motor drive chips, the valves position signal were measured by high precision potentiometer and sent to the MCUs multifunction analog input channel port via the multifunction port of analog to collect the valve position. The controllers were connected together by communication bus; a single controller could control four dilution water valves, which improved the integrated level and applicability. |
