摘要： With the position regulator according to the invention a first adjusting step and a second adjusting step are generated in order to prevent sustained oscillations about a constant desired value. The size of the first and second adjusting steps is such that, after the first adjusting step, the drive system is moved away from the desired value at least by the smallest increment and, after the second adjusting step, lies within a neutral zone in which a deviation is not corrected. Advantages of a pneumatic control valve with a position regulator of this type are lower air consumption and wear and greater regulating accuracy. The invention is used in pneumatic actuators.
