摘要
The invention relates to methods for two-point control of an actuator (1), based on a binary sensor signal (y) of a sensor unit (2), which detects an influenceable by the actuator (1) process variable (P) such that it exceeds a first switching value (Sw1 ) outputs a first sensor signal value (y1) and when a second switching value (Sw1, Sw2) falls below a second sensor signal value (y0), wherein the actuator (1) is controlled by a manipulated variable (u), which either a first control value (u1) or assumes a second control value (u2), the first control value (u1) and the second control value (u2) being dependent on a fall time (t_fall) corresponding to the duration of the first sensor signal value (y1) and a rise time (t_rise) the duration of the second sensor signal value (y0), in the operation of the actuator (1) are dynamically adjusted so that they converge to each other. In addition, the invention relates to a two-point controller (10) which is adapted to carry out the method, and an actuator (1) comprising this two-position controller (10).
