Robust Process Control With Saturated Control Input

The contribution presents a methodology to design a robust control loop in case of the saturated control input. The control system design is based on the polynomial approach resulting in the pole-placement problem to be solved. This task is addressed numerically by means of standard MATLAB functions to meet both the constraints on the control input and robustness of the resultant loop. New control quality criteria are suggested for this purpose. The proposed methodology is illustrated practically on a simple simulation example with a classical feedback set-up and one optimized parameter. The presented preliminary results show applicability of the suggested approach.
