Abstract
A priori knowledge about the process is often available when designing an adaptive controller. This report describes a method to use this knowledge. <br><br> The first step is to design a nominal controller. In the following steps the nominal controller is modified adaptively. The principal advantage of this method over conventional methods is that the calculations are minimized. <br><br> In this report the method has been investigated through two examples. The adaption has been carried out using approximations of increasing complexibility. Simulations show that for reasonable deviations of the process parameters from the nominal values, considerable improvement in performance is achieved with the adaptive controllers compared to the...
