Application of fuzzy Smith intelligent control in automatic control system of cone crusher

The control system of cone crusher is a big inertial system with nonlinearity and pure time-delay. According to this, the Fuzzy PID and improved Smith predictor are presented. The design combines Fuzzy PID with a good dynamic performance and good robustness, and uses improved Smith predictor to overcome effects of the controlled object parameter changes. Simulation results show that the intelligent control system can improve the stability and dynamic performance of system.
