Abstract
For controlling multivariable systems, a control unit for controlling a system with several coupled control variables. The control unit includes controllers ( ) having associated control variables (x , x ) as well as a decoupling network. The decoupling network is connected upstream from the system and includes at least one first decoupling member ( ). A first output variable (y ) of a first one of the controllers ( ) is routed to the first decoupling member ( ). The first decoupling member generates a first correcting quantity ( ) for a second output variable (y ) of a second one of the controllers ( ). The second controller ( ) has a PI- or PID-controller core ( ) and is configured such that integrator windup is eliminated when the second output variable (y ) corrected with the first correcting quantity ( ) reaches a manipulated variable limit. Bumpless manual/automatic changeover of the controller is also made possible.
