摘要：

A simple method has been investigated for the total or partial removal of the effect of non-linear process phenomena in multi-variable feedback control systems. The method is based upon computing the control variables which will drive the process at desired rates. It is shown that the effect of model errors in the linearization of the process can be partly removed through the use of large feedback gains. In practice there will be limits on how large gains can be used. The sensitivity to parameter errors is less pronounced and the transient behavior is superior to that of ordinary PI controllers.
