A new control method is proposed for tension control in a paper processing machine. This method is based on an algorithm of PID control improved by a feedforward neural network which compensates the dynamic changes and extern perturbations. This method will be called PID-RNA controller in advance. The union of both methods of control was realized adding the control signals generated by both algorithms of control. The tension is measured by a tension sensor which provides a electric signal proportional to the mechanical tension to a digital signal processor (dsPIC30F4011), this processor determines the control signal and send it to a power driver that control an actuator that could be a alternating current motor, a direct current motor or a brake. In the case of the alignment control an optical sensor detects if the material, in this case paper, is aligned correctly, the actuator that aligns the paper could be a direct current motor or a steeper motor. The actuator operates a mechanical system that guides the paper. A simulation is of the industrial application is realized for get a better realism, in addition it was proved in a paper processing machine. The remarkable disturbance rejection capability of a PID-RNA controller is also demonstrated and the results show the effectiveness of the controller proposed.
