In process industries, PID control has been applied to controlled objects such as chemical plants. A cascade control system is applied in order to improve control performance by using several feedback loops. However, it is complicated to design a cascade control system because this control system includes several controllers. In this paper, a design scheme of data-oriented cascade control system without using system models is proposed. According to the proposed scheme, PID gains of several controllers can be derived by using only closed-loop data. The effectiveness of the proposed method is verified by using a simulation example.
