Design-for-Control-Based Integration

An integrated design and control method is presented in this chapter for the nonlinear system with hybrid discrete/continuous variables. First, in order to simplify controller design, a design-for-control approach is presented to make the complex system to have a well linear approximation and controllable property. This integration method has the following characteristics: system task is shared by discrete design and continuous control: the easy-control property is considered at the stage of process design, upon which a simple controller will be designed latter for a robust global performance. Then, the robust design and control is integrated to guarantee system stability as well as the robust pole placement. Finally, effectiveness of this integration method is demonstrated first on the numerical simulation and then on the real manufacturing process.
