  • Digital proportional integral and derivative control system
    Patent number: 5268626
    Abstract: The invention relates to control and, more particularly, to digital control of the relative positioning of an inertia system in translation or rotation.According to the invention, the position of the variable to be adjusted is defined digitally and this information is then processed to obtain the integral, to the first derivative and the second derivative. According to the invention, this second derivative is used to produce an automatic correction of the parameters to be applied to the integral, to the first derivative and to the position data in order to calculate the force or torque to be applied to the inertia system.Use for the adjustment of translation or rotation movements.
