NON-LINEAR CORRECTING DEVICE Russian patent published in 1994 - IPC

FIELD: automatic control systems. SUBSTANCE: device has three units 1, 2, 3 for signal scaling, two adders 4, 5, two multipliers 6, 7, normally-closed switch 8, three units 9, 10, 11 for determination of signal sign, unit 12 for determination of positive sign of signal, unit 13 for determination of negative sign of signal, two logical one shapers 14, 15, differentiating unit 16, integrator 17 having resetting unit, exponential function unit 18. Device design decreases effect of integration errors on frequency characteristics of device, transmission coefficient change depending on sign of speed of output signal absolute value when input and output signals have same signs. In addition effect of alteration in order of integration on integration errors is decreased. EFFECT: increased functional capabilities. 4 dwg
