Operator based Nonlinear Control Design for a Water Level Process System

In this paper, a method of nonlinear control systems design for a water level process is proposed. This design method uses operator based robust right coprime factorization for the nonlinear process system, as a result, robust stability of the nonlinear process system is guaranteed. For the obtained robust stable process system, an operator based process tracking controller is also designed to realize the desired output tracking performance and to eliminate the disturbance of the process system input. A simulation result obtained to a water level process control system is given to show the effectiveness of the proposed method.
