PNEUMATIC DEVICE FOR CONSTRUCTION OF SELF-EXCITED SELF-ALIGNING SYSTEMS Russian patent published in 1995 - IPC

FIELD: automatization means. SUBSTANCE: device has extremum indicator, comparison elements, integrators, switching-over relay, summing amplifiers, master unit and choke adders. Process of adaptation of device to changing properties of object and medium is implemented by input of correction signals changing width of hysteresis zone of device and value of control action. Correction of first parameter provides for stabilization of frequency of self-oscillations and correction of second parameter stabilizes amplitude. EFFECT: expanded application field. 3 dwg
