The adhibition research of filling paste preparation system based on fuzzy PID control algorithm

The filling paste blending system is the core part in a paste backfill mining scheme. Its precision directly determines the flow properties and condensation curing performance of the filling slurry, thus it affects the filling effect of the underground mining working face. The research fuzzy PID control algorithm is introduced into the filling paste blending automatic control system in order to achieve a better control effect (Geng, 2007). Detailed introduces fuzzy PID controller design process, through the simulation experiment shows that fuzzy PID controller improves the system of external disturbance, and adapt to the internal parameters change robustness, ensure the precision of the burden system.
