FIELD: automation, possible use in systems for controlling dynamic objects in chemical industry, power engineering, tool-making industry.
SUBSTANCE: device contains extreme point indicator, relay block, adder, switch, zero-organ and is a two-positional controller with alternating hysteresis, value of which linearly depends on auto-oscillation amplitude of controlled coordinate. Special feature of the controller is that hysteresis in it may be either positive or negative.
EFFECT: expanded functional capabilities, possible measurement of amplitude and frequency of auto-oscillations in broad range during usage of the device in control systems.
