This paper presents a proportional integral derivative controller design method for the industrial process plant. The industrial process plant is represented by a second-order plus delay-time system. In order to simplify controller design, a pole compensation scheme is proposed to tune the controller parameters. By using the pole compensation to the system dynamic time constant, some controller parameters...
A decoupling dual internal model controller matrix design method is proposed for multi-variable time-delay input-output system in industrial processes, System responses can be almost decoupled. By using NLJ algorithm to simplify the order of analytical model or similar treatment, the calculated amount for deduce the matrix of decoupler is reduced. The method which uses dual-internal mode structure...
Nonlinear model predictive control algorithm based on hierarchical optimization is used in this paper to solve the thorny problems of controlling the pH, such as highly nonlinear and large time-delay which have been hard to be settled by the conventional PID controller, in the neutralization process of rolling mills wastewater treatment. Furthermore, the hardware parameters and configurations are...
