First of all, the minimum principle of Pontryagin are introduced to define the optimal control problem. Moreover, the concept of Extremal control is utilized in the performance. With the control of bang-bang type, the system would be manipulated. In addition, Singular control theory is applied to avoid the complex problem of the two point boundary value problem. According to the optimal construction indicated above, the optimal design of fed-batch bio-reactor and tubular flow reactor would be operated individually. Finally, the study proceeds the robust test in order to maintain the best condition of this system by using nonlinear model predictive control which can remove the disturbance, and to maintain the system at the optimal condition.
