Abstract :
In this paper, operator-based robust nonlinear control is considered for a twin-tank water level process with input constraint. The concept of mapping is introduced for the operator based method, which is not influenced by the input signals and has a strong anti-interference ability. Firstly, mathematical modeling is discussed. And then, the controller is designed by using robust right coprime factorization based on operator theory. Furthermore, considering input constraint, operator-based sliding mode nonlinear control is presented for the twin-tank water level process. Finally, simulation results are given to show the effectiveness of the proposed method.
