Abstract (en)

[origin: WO2020001974A1] The invention relates to a method for the two-position control of an actuator (1) on the basis of a binary sensor signal (y) of a sensor unit (2), which senses a process variable (P), which can be influenced by the actuator (1), in such a way that the sensor unit outputs a first sensor signal value (y1) when a first switching value (Sw1) is exceeded and a second sensor signal value (y0) when a second switching value (Sw1, Sw2) is fallen below, wherein: the actuator (1) is controlled with a manipulated variable (u), which assumes either a first control value (u1) or a second control value (u2); the first control value (u1) and the second control value (u2) are dynamically adapted during the operation of the actuator (1), in dependence on a fall time (t_fall) corresponding to the duration of the first sensor signal value (y1) and a rise time (t_rise) corresponding to the duration of the second sensor signal value (y0), in such a way that the first and second control values converge. The invention further relates to a two-position controller (10) designed to carry out the method and to an actuator (1) comprising said two-position controller (10).
