滞后的

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...

Because of the influence of the planned economy, Chinese media, especially Chinese television have problems in personnel system. The reasonable competition system, hortatory system and providing system are not yet set up. The Newcomers have to accept their position at the bottom of the pecking order. Thus it can hardly make everyone develop his capability completely. The fair environment in which manpower could be distinguished himself is not yet existed. The system which could keep manpower, attract manpower and make him develop his whole capability is not yet set up. The variety problems of the traditional personnel system seriously interfere with the development of Chinese television.
