Internal Model Control with State Affine Representation Methodology and Application Software

This paper describes an approach that leads to the synthesis of robust controllers. In a methodological part, we recall the main features of the Internal Model Control, and of the state affine representation of varylinear systems. After that, we show how these two methods can be combined to improve the robustness of control algorithms. In the next section, we describe an application software. Its main aims are to allow an easy simulation of the above mentionned control structures, associated with different types of processes and additive disturbances. The last part deals with several results of simulation: we show the versatibility of that application software and some contributions of these different methods to the synthesis of robust control.
