Control of particle flow by numerical analysis using the particle element method

This paper deals with the control of particle flow which is simulated by numerical analysis using the particle element method. First, a simulation model using the particle element method was made. Because it is difficult to find the mathematical model which shows the entire behavior of the particles, the relation between the gap of the hole and flow velocity is approximated as a first order system from the simulation. Then, PI control gain was adjusted in that first order system and renewed on the simulation.
