ABSTRACT:
A dynamic control system includes at least one control loop which contains a comparator, a correction device and an adjusting device with a control device wherein a controlled variable is determined and compared with a reference variable for forming a control difference, the correction and the adjusting device operating to provide a given characteristic, a controlled variable being derived by the adjusting device cooperating with a control variable derived from the control device as the output variable wherein the control loop can be coupled to at least one further control loop and/or variable of the dynamic control system, wherein the further control loop includes an adjusting device and wherein the control device contains at least two functional groups having different characteristics, of which at least one is intermittently connected in the signal path of the control difference for generating the controlled variable and a method for operating the dynamic control system.
