查询词典 inertial system

Chain-grate bed temperature field is a large inertial, nonlinear and time delays controlled system.Its math model is not easy to figure out.Three Fuzzy-PID controllers are presented in this paper based on the dynamic character of fuzzy control and the static character of PID control.They are simulated via combining fuzzy logic toolbox with Simulink.The simulation result shows that they have better characters both in dynamic and static than general PID controller.At the same time, they have better robustness...
