The process with constraint In this paper, operator-based sliding-mode nonlinear control is presented for a process with input constraint. After the mathematical model is discussed for the water level process, it is seen that there exist uncertainty and input constraint in the process. Operator-based robust nonlinear control is then considered by using robust right coprime factorization method to eliminate the effect of uncertainty. Furthermore, operator-based sliding-mode nonlinear control is proposed to deal with the constrained input. Finally, simulation and experimental results are given to show the effectiveness of the proposed method.
