Research of Steam Temperature Control System in 600MW Super-critical Unit
In the modern thermal power plant, the superheated steam temperature is one of the main parameters of the boiler, which is very important for unit’s safety. Aiming at the characteristics of large inertia and non-linearity, the main steam temperature system is controlled using state variable and multi-model. State feedback is used to compensate the large [...]
Coordinate Control on Variable Air Volume Air-Conditioning System
Variable air volume (VAV) air-conditioning system is superior to the other air-conditioning systems for its economic and flexible performance, which has been the main current of air-conditioning system effectively. However, the VAV air conditioning control system is a great inertia, pure lag, high nonlinear and strong coupling complex system, so the conventional PID control can’t [...]
Research on Control System of Consequent-pole Bearingless Permanent Magnet Motor
As the special rotor structure of consequent-pole bearingless permanent magnet motor, the coupling of the motor between the levitation and torque system is greatly weakened. So the control system of the motor can be designed respectively. The reliability of the whole system is enhanced. Thus, it has extensive applied foreground in national defence, industry, agriculture, [...]
The Application and Research of Robust Fuzzy Control in the Control of Circulating Fluidized Bed Boiler
