PCT No. PCT/DE94/00575 Sec. 371 Date Nov. 27, 1995 Sec. 102(e) Date Nov. 27, 1995 PCT Filed May 18, 1994 PCT Pub. No. WO94/28470 PCT Pub. Date Dec. 8, 1994A controlling system includes a comparator unit, which determines a system deviation from a reference variable and a controlled variable, and comprising a correcting device, which is arranged downstream from the comparator unit and which determines a manipulated variable of a controlled system. As a result, the controlling system acts quickly on this manipulated variable in that, from the controlled variable, a differential device determines a difference quotient and supplies it to the correcting device. The correcting device, in accordance with a control instruction, from the difference quotient and the system deviation, starting from an instantaneous state, selects a sequential state and acts on the manipulated variable in accordance with this sequential state. The invention is used in programmable controllers.
