Modeling and optimal control based on moving pattern

For a class of complex production process systems, in our previous work, we have proposed a modeling and control method based on moving pattern. Based on our previous work, in this paper, a new optimal control method is presented. First, based on the historical data, by constructing “pattern moving space”, a dynamics description method based on moving pattern is given. Furthermore, the optimal control method is proposed based on moving pattern. In this method, by variable substitution, the system dynamics description based on moving pattern is converted to the form of state equation. Then the optimal controller is designed by using discrete-time system minimum principal. At last, some simulations based on the actual running status data collected from 400 sinter machine of Anyang iron and steel plant are given to verify the feasibility.
