摘要
For controlling multivariable systems, a control unit for controlling a system with several coupled control variables. The control unit includes controllers (10, 11) having associated control variables (x1, x2) as well as a decoupling network. The decoupling network is connected upstream from the system and includes at least one first decoupling member (12). A first output variable (y1) of a first one of the controllers (10) is routed to the first decoupling member (12). The first decoupling member generates a first correcting quantity (14) for a second output variable (y2) of a second one of the controllers (11). The second controller (11) has a PI- or PID-controller core (40) and is configured such that integrator windup is eliminated when the second output variable (y2) corrected with the first correcting quantity (14) reaches a manipulated variable limit. Bumpless manual/automatic changeover of the controller is also made possible.
